AbstractNetwork and Sharing Center is your main portal into the networking components of Windows. It

provides services to view, configure, and troubleshoot your network access. The features in

Windows Vista and Windows Server 2008 allow you to view your network health network at a

glance, see your network displayed graphically, configure folder sharing, set up new connections

to remote systems using VPN or dial-up networking and manage your wireless network

connections.

Introduction to Administering Network and Sharing Center

This guide explains how to administer Network and Sharing Center. These activities are part of

the operating phase of the information technology (IT) life cycle. If you are not familiar with this

guide, review the following sections of this introduction.

When to Use This GuideUse this guide when:

You want to create, configure, or manage a network connection to a wireless or remote

network.

Configure network features for your client computers in a managed network.

This guide can be used by organizations that have deployed Microsoft® Windows Vista® and

Windows Server® 2008. It includes information that is relevant to different roles within an IT

organization, including IT operations management and administrators. This information provides

management-level knowledge of Network Center and the IT processes required to operate it.

In addition, this guide contains more detailed procedures that are designed for operators who

have varied levels of expertise and experience. Although the procedures provide operator

guidance from start to finish, operators must have a basic proficiency with the Microsoft

Management Console (MMC) and snap-ins and know how to start administrative programs and

access the command line. If operators are not familiar with Network and Sharing Center, it might

be necessary for IT planners or IT managers to review the relevant operations in this guide and

provide the operators with parameters or data that must be entered when the operation is

performed.

How to Use This GuideThe operations areas are divided into the following types of content:

Objectives are high-level goals for managing, monitoring, optimizing and securing Network

Center. Each objective consists of one or more high-level tasks that describe how the

objective is accomplished. In this guide, Using Network and Sharing Center is an example of

an objective.

Tasks are used to group related procedures and provide general guidance for achieving the

goals of an objective. In this guide, Creating and Configuring Network Connections is an

example of a task.

Procedures provide step-by-step instructions for completing tasks. In this guide, Display the

Network Map is an example of a procedure topic.

16

If you are an IT manager who is delegating tasks to operators within your organization, you might

want to:

Read through the objectives and tasks to determine how to delegate permissions and

whether you need to install tools before operators perform the procedures for each task.

Before assigning tasks to individual operators, ensure that you have all the tools installed

where operators can use them.

When necessary, create “tear sheets” for each task that operators perform in your

organization. Copy and paste the task and its related procedures into a separate document,

and then either print these documents or store them online, depending on the preference of

your organization.

See AlsoBest Practices for Administering Network and Sharing Center





The following best practices simplify operations and ease administration of the network

connections on your computer:

If you are an administrator, do not give other users network access until you have

turned off the Network Location Wizard either for your network, or for a specific user,

by creating a new registry entry.

Standard users cannot change the network location. Unless your network is part of a domain,

the default setting for your network is Public location. If your network is not part of a domain,

the Public location setting is recommended.

For more information, see Start Network and Sharing Center.

When using multiple network adapters, rename each local area network connection.

Windows detects network adapters and automatically creates a local area connection in the

Network Connections folder for each network adapter. If more than one network adapter is

installed, you can eliminate possible confusion by immediately renaming each local area

connection to reflect the network to which it connects.

For more information, see Rename a Network Connection.

17

Verify required connection settings for your network adapter.

If your network administrator or Internet service provider (ISP) requires static settings, you

might need one or more of the following:

A specific IPv4 or IPv6 address.

One or more Domain Name Service (DNS) addresses.

A DNS domain name.

A default gateway address.

One or more Windows Internet Name Service (WINS) addresses (for IPv4 networks

only).

Dynamic Host Configuration Protocol (DHCP) is enabled by default. This gets your IP

address and other configuration information automatically from a service on your network.

Automated IP settings are used for all connections, and they eliminate the need to configure

settings such as DNS, WINS, and so on.

For more information about enabling DHCP, see Configure TCP/IP Settings.

Create dial-up, VPN, or broadband connections by using the Set up a Connection or

Network page.

After you create a connection, you can copy the connections, rename them and modify the

connection settings. By doing so, you can easily create different connections to

accommodate multiple modems, ISPs, dialing profiles, and so on.

For more information, see Create a Copy of a Network Connection.

Specify the order in which network providers and protocols are accessed.

By changing the order of protocols bound to network providers, you can improve

performance. On many networks, you will use only TCP/IPv4. However, as you introduce

TCP/IPv6 to your network, you can move Internet Protocol Version 6 (TCP/IPv6) to the top

of the File and Printer Sharing for Microsoft Networks and the Client for Microsoft

Networks bindings on the Adapters and Bindings tab.

For more information about modifying the order of protocol bindings, see Modify the Protocol

Bindings Order.

Only install and enable the network protocols that you need.

Limiting the number of protocols on your computer enhances its performance and reduces

network traffic. Other protocols might be available to you. Install only those required for your

computer to communicate with the hosts you need.

If your computer encounters a problem with a network or dial-up connection, it attempts to

establish connectivity by using every network protocol that is installed and enabled. By only

installing and enabling the protocols that your computer can use, the operating system does

not attempt to connect with protocols it cannot use, and returns status information to you

more efficiently.

18

For more information, see Enable or Disable a Network Protocol or Component.

If Windows does not support your modem make and model, check the manufacturer's

Web site for the latest installation or .inf file.

The installation files, particularly for new modems, are often added or updated by

manufacturers. If you cannot find your modem listed in Windows, look in the manufacturer's

documentation to determine whether the modem has the same characteristics as another

supported modem.

For more information, see Installing and Configuring Modems and ISDN Adapters.

Use the Phone and Modem Options diagnostics tool to test and troubleshoot a

modem.

Windows includes a built-in diagnostic tool to communicate with your modem, report its

status, and ensure that it is responding properly to commands.

For more information, see Test a Modem, and Log and View Modem Commands.

Before you connect to another computer or online service provider, check the

hardware settings for your modem.

The data connection parameters for two modems need to be identical for them to connect

successfully. Refer to the documentation provided by your service provider for the correct

settings. Typical settings are:

Data bits: 8

Parity: None

Stop bit: 1

Most service providers use these settings. If these do not work, try seven data bits, even

parity, and one stop bit. A few online service providers use these settings. Other settings are

extremely rare.

For more information, see Changing Modem Data and Hardware Settings.

When you install the same make and model of modem on multiple ports, first install it

on one port, and then duplicate the installation for the remaining ports.

For more information, see Duplicate a Modem Installation on Multiple Ports.

To change the same setting for modems installed on multiple ports, first change the

setting on one modem and then copy the change to the remaining modems.

For more information, see Copy Modem Properties to Modems on Multiple Ports.

The Network and Sharing Center is the location for all of your network setup and configuration.

Microsoft® Windows Vista® and Windows Server® 2008 perform much of the network installation

and configuration for you. For wired and wireless networks, or connections to remote networks

over virtual private network (VPN) or dial-up links, Network and Sharing Center serves as your

tool to connect and disconnect these networks as required.

This section includes the following tasks and procedures for administering Network and Sharing

Center:

Start Network and Sharing Center

Start the Network Connections Folder

Display the Network Map

Connect to a Remote Network

Disconnect from a Remote Network

Creating and Configuring Network Connections

Enable or Disable Sharing and Discovery

Customizing the Appearance of Discovered Networks

Display or Hide the Network Icon in the Notification Area

Enable or Disable Network Activity Animation in the Network Icon

Enable or Disable Notification of New Networks

Repair a LAN or High Speed Internet Connection





Start Network and Sharing Center

You can use this procedure to disable the Network Location Wizard, and start Network and

Sharing Center.

20

Any user account can be used to complete this procedure. Review the details in "Additional

considerations" in this topic.

Disabling the Network Location WizardThe Network Location Wizard appears when a user first starts the Network and Sharing Center.

The Network Location Wizard provides a user with a choice between setting the default network

as Home, Work, or Public location. Unless your network is part of a domain, the default setting

for your network is Public location. If your network is not part of a domain, the Public location

setting is recommended.

If you are an administrator, you can turn off the Network Location Wizard, either for all users on a

machine or only for the current user, by creating a new registry key.

Following the procedure for creating the registry key HKLM\System\CurrentControlSet\Control\

Network\NewNetworkWindowOff disables the Network Location Wizard for all users on the

machine. The presence of this key disables the wizard; its value does not matter. When the

machine is connected to any new network and this key is present, the wizard does not appear for

any users using the machine.

To turn off the Network Location Wizard for all users on a machine

1. Click Start, and then click Run.

2. In the Open box, type regedit, and then click OK.

Registry Editor opens.

3. On the Edit menu, click New, and then click Key.

4. Enter the following registry entry:

HKLM\System\CurrentControlSet\Control\Network\NewNetworkWindowOff

Following the procedure for creating the registry key HKCU\Software\Microsoft\Windows NT\

CurrentVersion\Network\NwCategoryWizard\Show disables the Network Location Wizard for only

the current user. In order to disable the wizard for the user, the key must be present and its value

set to 0. When the machine is connected to any new network and the key is present, the wizard

You can use this procedure to connect your computer to a remote network by using a saved

connection profile. After establishing the connection, you can access resources on the remote

network according the permissions granted to you by the administrator on that network.

Connections that appear in the Connect to a network page include:

Wireless networks. Windows does not automatically connect your computer to a wireless

network until you configure the connection with any required security information, and then

specify that the network is to be connected automatically.

Dial-up and VPN connections that you have defined. Windows connects to these

networks only when you specify the connection type. You can configure one of your dial-up or

VPN networks as a default auto-dial network.

Connections created with the Connection Manager Administration Kit (CMAK). These

are administrator created and distributed connection profiles that can include advanced

security features and customization for a specific organizational network. For more

information about CMAK, see Connection Manager Administration Kit

Connect to a remote networkYou can use the following methods to connect to a remote network:

Using the Windows interface

Using a command prompt for a wireless network

Using a command prompt for a dial-up connection

Using a command prompt for a VPN connection

Connect to a remote network by using the Windows interface

To connect to a remote network by using the Windows interface

Right-click the Network icon ( ) in the notification area, and then click Connect to a

network.

2. Filter the list of connections to include only those of the type you want by selecting the

type from the Show list. You can select Wireless, Dial-up and VPN, or All.

3. Select your connection in the list of available connections.

4. Click Connect.

5. If the connection you select requires additional information, such as a user ID and

password, or a Wired Equivalency Privacy (WEP) or Wi-Fi Protected Access (WPA)

security key, Windows prompts you for the required information. After you supply all

required information, the connection is completed.


You can also start the Connect to a network page by clicking Start, and then clicking

Connect To.

If you just created the connection, you might need to click the Refresh button located above

and to the right of the list of available connections.

If you are prompted for credentials, and you want to log on to a domain, type your user name

and the domain name in one of two ways:

Your user principal name prefix (your user name) and your user principal name suffix

(your domain name), joined by the "at" symbol (@). For example,

[email protected].

26

Your domain name and your user name, separated by the backslash (\) character. For

example, sales\user.

Note that the suffix in the first example is a fully-qualified Domain Name System (DNS)

domain name. Your administrator might have created an alternative suffix to simplify the

logon process. For example, creating a user principal name suffix of "contoso" allows the

same user to log on by using the much simpler [email protected].

Instead of having to type your domain name, you can also configure your connection to

include your logon domain in the Connect ConnectionName dialog box, as follows:

a. Click Properties if the button is enabled.

b. On the Options tab, select the Include Windows logon domain check box.

After connecting to a remote network, you might not be able to see all computers on your local

network. This is because after you connect, your remote connection becomes your default path

for network routing. Consequently, you see computers on the remote network, and you see other

computers on the same LAN segment to which your computer is connected. But you cannot

communicate by using computers on networks that were previously reached through a router on

your local LAN.

Make a Local Area Network (LAN) Connection

Typically, most computers running Windows are connected to a local area network. When you

start your computer, Windows automatically detects your network adapter and creates the LAN

connection, and starts it. Unlike other types of connections, you do not have to manually start a

LAN connection.

If more than one network adapter is installed in your computer, you can eliminate possible

confusion by renaming each connection to reflect the network to which it connects. For more

information, see Rename a Network Connection.

You can use this procedure to create a connection to a wireless network. Windows fully supports

wireless network adapters that conform to the standard network specifications, including

IEEE 802.11.

By default, a wireless network adapter is enabled when installed, and begins listening for wireless

networks within range. For security reasons, Windows does not automatically connect to any

wireless network when it is first discovered. You must use the procedure shown here to start a

connection. After a connection has been made, Windows can be configured to always

automatically connect whenever that network is in range.


Making a wireless network connectionYou can make a connection to the following types of wireless networks:

To a network that is visible and in range

To a network that is not visible

Make a connection to a wireless network that is visible and in range

Most wireless network access points can be configured to broadcast its Service Set Identifier

(SSID) or to not broadcast it. If a wireless access point is broadcasting, then Windows can

discover it, determine the security requirements, and if you choose, connect to it.

You can use this procedure to create a VPN connection to a remote network. A VPN connection is

a method for allowing a computer to access a secured remote network by using a non-secure

network, such as the Internet, that lies between them.

43




The remote network requires a VPN host computer with two network connections: one to the

public network and one on the secured network. Microsoft provides this functionality in the

Routing and Remote Access server role included with Windows Server.

The client computer on the Internet establishes a connection to the VPN host, and the two

computers encrypt all data transmitted between them. When the VPN host receives a packet from

the client, it decrypts the packet and then retransmits it on the secure network. Traffic from hosts

on the secured network to the client pass through the VPN host computer, which encrypts the

information before transmitting it to the client over the public network.



Making a VPN connectionYou can use the following methods to make a VPN connection:

Over a LAN connection and the Internet

Over an existing dial-up or broadband PPPoE connection

7. In the Destination name text box, type the name for this connection that you want

displayed in Network and Sharing Center.

8. If the remote VPN host supports smart card authentication, then select Use a smart

card.

9. If this connection can be used by any user on this computer, then select Allow other

people to use this connection.

10. If you do not want to connect right now, then select Don't connect now; just set it up so

I can connect later. If you leave this check box unselected, then the computer attempts

to complete the connection as soon as you finish configuring the connection.

44

11. Click Next.

12. In the User name, Password, and Domain text boxes, enter the credentials that grant

you access to the remote network.

13. If you want the computer to remember these credentials and for each time you connect,

then select Remember this password.

14. Windows saves your network configuration so that it is available for use from the

Connect to menu.

15. Click Next.

One of the following results occur:

If you did select the Don't connect now check box, then Windows displays a page

that indicates that your connection is ready to use. You can use the connection by

clicking the Connect to my workplace now link, or click Close.

If you did not select the Don't connect now check box, then Windows immediately

attempts to connect to the network.


VPN connections are blocked by default by many software and hardware firewall products.

Make sure that any firewall software you run on this computer is configured to allow VPN

connections. Also, configure any firewall components on your network to allow VPN traffic to

pass through. For more information, see the documentation provided with your firewall

software or hardware device.

To make the connection available to all users, you must be logged on as a member of the

Administrators group or the Network Configuration Operators group.

You can create multiple VPN connections by copying them in the Network Connections folder.

You can then rename the connections and modify connection settings. By doing so, you can

easily create different connections to accommodate multiple hosts, security options, and so

on. For more information, see Create a Copy of a Network Connection and Rename a

Network Connection.

Make a VPN connection over a dial-up or broadband PPPoE connection

Creating a VPN connection over a dial-up or PPPoE connection involves creating the dial-up or

PPPoE connection and VPN connection separately, and then configuring the VPN connection to

use the dial-up or PPPoE connection instead of the Internet.

When you follow this procedure, you still have two connections listed in the Network Connections

folder, but you only have to start the VPN connection. Windows starts the dial-up or PPPoE

connection for you first, and then establishes the VPN connection in addition to the dial-up or

PPPoE connection.

45

You might want to consider naming your VPN connection in a way that indicates to you that it will

start a dial-up or PPPoE connection.

To make a VPN connection over a dial-up or broadband PPPoE connection

1. Make a Dial-up or ISDN Network Connection or Make a broadband connection using

Point-to-Point Protocol over Ethernet (PPPoE).

2. Follow the procedure Make a VPN connection over a LAN connection and the Internet

above to create a VPN connection over the Internet.

3. After you have created both connections, open the Network Connections folder.

4. Right-click your VPN connection, and then click Properties.

5. In the First connect box, select Dial another connection first, and then select your

dial-up or PPPoE connection in the list.

6. Click OK.






You can use this procedure to create a dial-up networking connection that uses your modem or

Integrated Services Digital Network (ISDN) adapter. Although an analog modem and a digital

ISDN adapter use very different technologies to transmit data, they are used in a similar way.

When you run a program that requires Windows to connect using a dial-up modem, it needs the

complete phone number, as well as instructions about how to dial that number. Depending on

where you are dialing from, you might or might not need to dial a long distance access number or

59

the area code. You might be in a location that requires that you dial 9 (or some other number) to

access an outside line before you can dial the destination number. You might also need to access

the network of an alternative phone carrier.

Windows supports all of these features by providing:

Locations. A location is associated with the place from which you are dialing. You can create

locations for your home, your work, or a location from which you always want to use a calling

card.

Dialing rules. Rules specify how a specific phone number is dialed from a specific location.

For example, a rule might specify that from a specific location you must always dial 9 first, in

order to access an outside line.

Area code rules. Area code rules specify how phone numbers are to be dialed from your

current area code into other area codes or within your area code.

Calling cards. Calling cards allow you to enter the information required for Windows to

connect to a specific phone carrier, including identification information, such as an account

number and a personal identification number (PIN) that grants you access to that network.

One important related item is configuring the modem properties to properly interact with the

phone system at your location. For more information, see Changing How Modems Initialize and

Connect.

You can use this procedure to configure rules that determine how phone numbers are dialed from

within a specific area code. Area code rules enable you to change the dialing patterns for calls to

numbers in the same country or region. The default area code rule for numbers in another area

code often requires the program to dial a country code, the area or city code, and then the phone

number. For numbers in the same area code, the program dials only the local phone number.


To specify an area code rule


Options.

2. On the Dialing Rules tab, click the location you want to modify, and then click Edit.

To create a new location, click New.

3. Click the Area Code Rules tab, and then perform one of the following options:

or long distance calls from within a private branch exchange (PBX), such as used by a

company or other organization.




64






You can use this procedure to create a new calling card. A calling card is used to specify the

additional numbers required to access the network of another phone carrier, identify your account

on that network, and provide your personal identification number (PIN) to provide security.


To create a new calling card

3. On the Calling Card tab, click New.

4. On the General tab, type the value for the following settings:

Calling card name: The name you use to identify the card.

Account number: The account number provided by the calling card company for the

calling card. For some calling cards this is the home or business phone number

associated with the account.

Personal Identification Number (PIN): Any personal number required to secure

your account against unauthorized use. Often a four digit number, this is usually

dialed after the account number when you place a call. Some calling cards do not

use a PIN.

5. On each of the Long Distance, International and Local Calls tabs, type the phone

number that is required to access the corresponding service. Include all the digits you

need to dial after you access an outside line:

On the Long Distance tab, Access number for long distance calls is the phone

number required to access the calling card service for domestic long distance calls.

On the International tab, Access number for international calls is the phone

number required to access the calling card service for international long distance

calls.

On the Local Calls tab, Access number for local calls is the phone number

65

required to access the calling card service for local calls. Leave this blank to dial local

numbers without using the calling card.

6. On each of the Long Distance, International and Local Calls tabs, in Calling card

dialing steps, click the following buttons to add it as a specific step needed to complete

a call:

Access Number: The number to access the calling card company. This will dial the

access number entered at the top of the tab.

Account Number: The account number that identifies your account, which was

entered on the General tab.

PIN: Your personal identification number, which was entered on the General tab,

usually dialed immediately after the account number.

Destination Number: The country/region code, area code, and phone number.

Wait for Prompt: Pauses dialing for a dial tone, voice message, or time interval.

Specify Digits: Any sequence of the digits 0-9, *, and #.

7. To reposition any step in the order of calling card dialing steps, click the step, and then

click Move Up or Move Down.

Important

When you enter a calling card PIN number, this number is displayed in plaintext.

Therefore, to enhance security, type this number in a private location whenever possible.

If you are not in a private location, take care to ensure that this number is not exposed to

another user.





If you add Access Number, PIN, or Account Number default steps to the Calling card

dialing steps and the corresponding field is blank, the program will prompt you to enter the

missing value when you click OK or Apply.

calling card to specify the dialing sequence. When you create the calling card for a long

distance carrier, create a unique location to go with it.




68






You can use this procedure to configure Windows to always dial your chosen long distance

carrier, rather than using the default carrier, for specified types of phone calls.


To specify a long distance carrier


Options.

2. On the Dialing Rules tab, click New.

3. On the General tab, type a Location name to identify the long distance carrier, and

specify the Country/region, Area code, and any Dialing rules.

distance carrier for Windows, and then click OK.

69





This procedure specifies long distance carrier (also called the long distance operator)

numbers required for domestic or international long distance calling. This procedure is not

normally required to use the default domestic and international long distance operators for a

country/region. The country/region selection for a location normally enables programs to use

the default numbers.

The location selected on the Dialing Rules tab of Phone and Modem Options is the default

location for dialing. If you create more than one location, some Windows allow you to choose

a different location before dialing.









Windows supports a variety of additional options that add more flexibility to your dial-up network

connections.

You can use this procedure to configure a remote access server to disconnect and then call you

back to reestablish the connection from the server to you. This transfers the bulk of any phone

charges to the remote access server, by having the remote access server dial back to your

location after you initially connect. It also improves security when the remote access server is

configured to call back only approved call back numbers.


To configure callback options on a network connection


2. Press ALT to display the menu bar.

3. On the Advanced menu, click Remote Access Preferences.

4. On the Callback tab, do one of the following:

If you do not want to use callback, click No callback.

If you want to decide whether to use callback at the time you connect, click Ask me

during dialing when the server offers.

If you want to use callback every time, click Always call me back at the number(s)

below, and then select the modem or device you want to be called back.

If Phone number is blank for the device you have selected, click Edit, and then type

the number.

If you want to remove a modem or device from the list of possible callback devices,

click the modem or device, and then click Delete.


Your system administrator can override any callback settings that you configure. Through

server settings, the administrator can deny the use of callback, allow you to set callback

options, or require callback to a particular number.

71

To use callback, Link Control Protocol (LCP) extensions must be enabled. For more

information, see Start or Stop Requesting LCP Extensions in PPP.

See AlsoConfigure Autodial








Configure Autodial

You can use this procedure to configure the locations from which your computer automatically

dials a default network connection when a network resource is requested, and no connection to a

network is currently active.

The network connection that is started is the one identified as your 'default' network connection.

In the Network Connections folder, the default connection is identified by a checkmark in a green

circle. To set a default connection, see Specify a Default Network Connection.


To configure autodial

1. Start the Network Connections Folder



4. On the Autodial tab, select the check box next to the location you want to enable

autodial, and then click OK.


Autodial is enabled by default in Windows Vista.

For example, if you have multiple dialing locations defined and you do not want to autodial

from the location "Home," but you do from all other locations, clear the check box next to

"Home," and then check all others.

72




See AlsoConfigure Client Callback Options









You can use this procedure to configure your computer to use multiple modems or ISDN links to

connect to a remote network. Doing so combines multiple physical links, which increases the

aggregate bandwidth of your connection. Windows can also dynamically dial and drop multilinked

lines as bandwidth demands rise and fall, keeping your performance at the level you want, while

minimizing your phone costs.


To enable multiple device dialing


2. Right-click the connection on which you want to enable the dialing of multiple devices,

and then click Properties.

3. On the General tab, under Connect using, select the check box next to each modem

you want to include in the connection.

4. Clear the Dial only first available device check box.


If you want to dial only the first available device, click Dial only first available

device.

If you want to use all of your devices, click Dial all devices.

If you want to dynamically dial and hang up devices as needed, click Dial devices

73

only as needed, and then click Configure.

In Automatic dialing, click the Activity at least percentage and Duration at least

time you want to set. Another line is dialed when connection activity reaches this level

for the amount of time that you specify.

In Automatic hangup, click the Activity no more than percentage and Duration at

least time you want to set. A device is disconnected when connection activity

decreases to this level for at least the amount of time that you specify.


If you selected Dial devices only as needed, the last multilinked device ignores the

Automatic hangup setting, and a 20-minute time-out is used for the last device.

If you use multiple devices to dial a server that requires callback, then only one of your

multilinked devices is called back. This is because only one number is stored in a user

account. Therefore, only one device connects and all other devices fail to complete the

connection, and your connection loses multilink functionality.

You can avoid this problem if the multilinked phone book entry is an ISDN with two channels

that have the same phone number.

Multiple device dialing is available only if multiple adapters are available on the computer.

If you select Dial all devices, dropped links in the multilinked bundle are not automatically

reinitialized. You can force links to reinitialize by selecting Dial devices only as needed, then

Configure, and then setting easily achieved Automatic dialing conditions which cause

another line to be dialed. For example, set Activity at least to 1 percent and Duration at

least to 3 seconds.

2. Right-click the dial-up connection you want to configure, and then click Properties.

3. On the General tab, modify the phone number by using one or more characters from the

following list.

Character Function

, (comma) Pauses briefly (two seconds for most

modems) before continuing.

P Switches from touch-tone to pulse/rotary

dialing.

T Switches from pulse/rotary to touch-tone

dialing.

$ Waits for a calling card prompt tone.

For example, when you dial in from a hotel room, you might have to add 9 to the number you

are calling to get an outside line. Your number might look similar to the following number:

9,555-0100

The comma after the 9 gives a pause long enough to get an outside line before continuing to

dial the full number.


By selecting the Use dialing rules check box, and then clicking Dialing Rules, you can

create a Location for which specific dialing rules automatically apply. For example, if you

frequently connect from home and need to disable call waiting, you can create a location for

use from home that automatically dials the code to disable call waiting before the connection

call is placed.

If you see unfamiliar characters being dialed before your number, check to make sure the

Use dialing rules check box is not selected, or ensure that the location selected is relevant

to the location from which you are dialing. If an incorrect location is selected, a location may

75

be enforcing a dialing rule that you do not need. For example, a location might be selected

that always dials 1 to accommodate long distance dialing.


Configure Autodial








You can use this procedure to configure how Windows attempts to redial phone calls that are not

successfully completed. You can configure how many times and how frequently Windows

attempts until it succeeds, and whether Windows automatically tries to reconnect if the

connection is dropped.


To configure redial options



3. On the Options tab, in Redialing options, click the arrows to set the number of times

the dial-up connection is automatically redialed if the first attempt to connect fails.

4. In Time between redial attempts, click the down arrow to set the amount of time to

pause between the end of one attempt and the beginning of another.

5. If you want the connection to automatically redial if the line is dropped, select the Redial

if line is dropped check box.


The Time between redial attempts pause lets the device reset itself before redialing. The

default is one minute. If that is not enough time, increase this setting. You can also

76

experiment with shorter times, but if you make the pause too short, the device does not have

time to reset itself.

If you are using Internet Explorer, the default browser settings for dial-up connections might

conflict with these redial options.


Configure Autodial








You can use this procedure to configure how long Windows will allow a dial-up connection to

remain idle before it disconnects the call.


To configure the idle time before disconnect



3. On the Options tab, in Redialing options, set Idle time before hanging up to the

amount of idle time you want to allow before the client hangs up a connection.


Keep in mind that the remote access server might also have a disconnect timer. If Idle time

before hanging up is set to a high time-out number, there is no guarantee that the

connection will not disconnect before the time passes. This is because the server might

disconnect you before the time set here.

77


Configure Autodial








You can use this procedure to assign multiple phone numbers to a dial-up network connection.

Sometimes the network to which you are calling has multiple access points in your city, and it

could also have access points in other nearby cities. You can assign all or several of the available

phone numbers to the connection, and establish the order in which you want Windows to try

them. If the first one does not connect successfully for any reason, Windows then tries the next

connection in order, and continues down the list until a successful connection is made.


To assign multiple phone numbers to a connection


2. Right-click the dial-up connection to which you want to assign multiple phone numbers,

and then click Properties.

3. On the General tab, in the Phone number section, click Alternates.

4. If you want the connection to attempt a different phone number when the first number in

the list is not successful, select the If number fails, try next number check box.

5. If you want the connection to move the first successful phone number to the top of the list

under Phone numbers and use it on the next connection attempt, click Move

successful number to top of list. This option has the effect of sorting the numbers to

help reduce the time it takes to connect successfully.

6. To add a new phone number to the list, click Add, and then in Phone number, type the

phone number. If you want the connection to use established area code and dialing rules,

select the Use dialing rules check box. Click OK when you finish typing the number.

78

7. If you want to change the order of phone numbers, under Phone numbers, select a

phone number, and then click the Up or Down arrow button until the phone numbers are

arranged in the order you want.

8. If you want to remove a phone number, under Phone numbers, click the phone number,

and then click Delete.


Configure Autodial








You can use this procedure to configure your computer to allow you to manually dial a number, or

to give you an opportunity to call an operator and have the call dialed for you.


To enable operator assisted calls or manual dialing


2. Press ALT to display the menu bar, and then on the Advanced menu, click Operator-

Assisted Dialing.

3. Double-click the connection you want to dial.

4. Pick up the telephone handset, and then dial the number or ask the operator to dial it for

you.

The number assigned to the entry is displayed in the dialog box for easy reference.

5. Immediately after you have finished dialing, click Dial.

6. Hang up the handset only after the modem takes control of the line, which is typically

signaled by a click followed by silence.

79

7. It is always safe to replace the handset after Network Connections begins verifying your

user name and password. The status message will remind you of this.


If operator-assisted dialing is enabled, a check mark appears next to Operator-Assisted

Dialing on the Advanced menu.


Configure Autodial








You can use this procedure to start the Remote Access Auto Connection Manager service. This

service connects your default network connection whenever a program requests a remote DNS

address or NetBIOS name, and a connection is not currently active to support the request.

In addition to allowing you to dial out from your computer to connect to another computer or

network, Windows also allows you to dial-in to your computer from another location over a

modem connection.

Windows Vista supports two types of incoming connections. You can configure your computer to

support incoming connection through a modem or through a virtual private network (VPN) over

the Internet.

To complete this task, perform the following procedures:

1. Accept Incoming Network Connections

2. Grant Incoming Connections Access Rights to Your Computer

3. Configure an Incoming Connection to Use TCP/IP

4. Configure an Incoming Connection to Use Callback





81





Accept Incoming Network Connections

You can use this procedure to enable incoming dial-up or VPN connections to your computer.



To accept incoming network connections


2. Press ALT to display the menu bar, and then on the File menu, click New Incoming

Connection.



4. On the Who may connect to this computer? page, select the users to whom you want

to grant access to your computer.

5. On the How will people connect? page, select one or both of the following options:

Through the Internet. This allows remote computers that are also attached to the

Internet to establish a connection to your computer by using a VPN.

Through a dial-up modem. Also, select the modem or modems you want to use.

6. Select the Networking software you want to support by using this dial-up connection. If

a protocol has configurable options, you can click Properties to configure the protocol to

meet your requirements. For more information, see Configure an Incoming Connection to

Use TCP/IP.

7. When you are done configuring the protocols, click Next.

Windows displays a list of the users that now have incoming access to this computer.

8. Click Close.


You can only have one incoming network configuration at a time. If you use the New

Incoming Connection menu to try to create a new one, Windows instead reconfigures your

existing incoming connection.

82

For large numbers of incoming connections on a server that operates as part of a distributed

network or as a domain controller, use Routing and Remote Access to create a remote

access server.

If your incoming connection and fax service have problems working together (for example,

you cannot receive incoming connection calls on a device enabled to receive faxes), the

modem might not support adaptive answer. Check your modem documentation to verify that

you need to disable Fax Receive for that device to accept incoming connections.

You can use this procedure to configure how Windows assigns TCP/IP addresses to remote

computers that attach to your computer by using an incoming dial-up or VPN connection. You can

configure your computer to:

Assign an IP address to the remote computer by using the DHCP server on your network

(IPv4 only).

Assign an IP address from a static pool of addresses (IPv4) or a range of prefixes (IPv6).

84

Allow the client computer to assign its own address (IPv4 only).

In addition, you can limit access from the remote computer to only resources available on the

host computer, or to any resource accessible through the network connections of a host

computer.



You can use the following methods to configure an incoming connection:

Using IP version 4

Using IP version 6

Configure an incoming connection to use IPv4

To configure an incoming connection to use IPv4



3. On the Networking tab, click Internet Protocol Version 4 (TCP/IPv4), and then click

Properties.

4. If you want incoming users to be able to access the local area network on which the dial-

up host computer resides, select the Allow callers to access my local area network

check box.


If you want to automatically assign a TCP/IP address to the incoming computer,

select the Assign TCP/IP addresses automatically using DHCP check box.

If you want to specify a TCP/IP address for the incoming computer, click Specify

TCP/IP addresses, and do the following:

In From, type the starting IP address.

In To, type the ending IP address.

Based on the addresses you type in From and To, the number of addresses that are

allocated is displayed in Total. The starting and ending IP addresses that you choose

depend on the originating address space and the number of addresses needed.

For more information on defining IP addresses for incoming connections, see

Planning TCP/IP Addressing [Preliminary].

6. If you want incoming connections to be able to use a self-defined TCP/IP address, select

the Allow calling computer to specify its own IP address check box.

7. Click OK to save your changes.

85


Most TCP/IP networks use subnets in order to effectively manage IP addresses. The closest

matching subnet is calculated for the range that you specified in From and To. The range of

addresses in the closest matching subnet might exceed the range that you specified. Unless

the addresses specified in From and To are subnet boundaries, the range based on the

calculated subnet will be larger than the range that you specified. To avoid this, specify a

range that falls on subnet boundaries. For example, if you are using the 10.0.0.0 private

network ID for your intranet, a range that falls on subnet boundaries is 10.0.1.168 to

10.0.1.175. Or, if you are using the 192.168.0.0 private network ID for your intranet, a range

that falls on subnet boundaries is 192.168.1.0 to 192.168.1.255.

If you select Allow callers to access my local area network or Allow calling computer to

specify its own IP address, these changes take effect immediately.

If you select Assign TCP/IP addresses automatically using DHCP, but there is no DHCP

server available, random addresses from the range 169.254.0.1 to 169.254.255.254 are

assigned.

You can use this procedure to configure your dial-up host computer to automatically call back the

calling computer when it attempts to connect.

This allows the host computer to be responsible for any phone charges incurred, and also can

provide a level of security when you limit the phone numbers to which Windows will call back a

client computer.



To configure an incoming connection to use callback



3. On the Users tab, click the user for which you want to configure callback, and then click

Properties.

4. On the Callback tab, do one of the following:

If you do not want to use callback for incoming connections, click Do not allow

callback.

If you want to give incoming connections the option of setting a specific callback

number, click Allow the caller to set the callback number.

If you want to consistently use the same callback number, click Always use the

following callback number, and then type the number.


Using a preset callback number provides some additional security because a user can only

successfully complete the connection if the call is made from the specified phone number.

That security comes at the cost of flexibility however, and is not a useful option for users who

travel to different locations.

87





All of your network connections have some settings in common, no matter what type of network

they connect to. The procedures in this task enable you to choose and configure which network

components are installed, which are used by each connection, and the order in which they are

7. On a local area connection, selecting the Obtain an IP address automatically option

enables the Alternate Configuration tab. Use this to enter alternate IP settings if your

computer is used on more than one network. To configure DNS, WINS, and IP settings,

click User configured on the Alternate Configuration tab.


Use automated IP settings (DHCP) whenever possible for all connections because they

eliminate the need to configure settings such as IP address, DNS server address, and WINS

server address.

The Alternate Configuration settings specify a second set of IP settings that are used when

a DHCP server is not available. This is very useful for portable computer users who often

switch between two different network environments such as DHCP and static IP network

environments.

See AlsoInstall Additional Network Protocols or Components








You can use this procedure to install additional networking components to Windows. Those

components can be new clients, services, or protocols that are associated with one or more of

your network connections.

By default, all of the clients, services, and protocols included with Windows that can be

associated with a connection are already installed. Use this procedure if you have a third-party

component that you want to add. If you removed a component from a connection, then you can

use this procedure to reinstall it to the connection.



91


To install an additional protocol or component



3. Right-click your connection, and then click Properties.

4. Click the Networking tab.

5. Click Install.



7. In the Select Network Feature Type dialog box, select Client, Service, or Protocol, and

then click Add.


If the component is in the list, select it, and then click OK.

Otherwise, click Have Disk.

9. Follow the instructions displayed to complete the installation.


After you add a new protocol or component, it is automatically available for every network

connection. Configure each connection to only use those protocols and components required

by that component. For more information, see Enable or Disable a Network Protocol or

Component.

Network protocols and components that were designed for earlier versions of Windows might

not run successfully in Windows Vista or Windows Server 2008. Check with the software

component vendor to ensure that it is compatible before installing it.

See AlsoConfigure TCP/IP Settings







92


You can use this procedure to enable or disable a network protocol or component on a specific

network connection.

Network performance is enhanced and network traffic is reduced when only the required

protocols and clients are enabled. If your computer encounters a problem with a network or dial-

up connection, it attempts to establish connectivity by using every network protocol that is

installed and enabled. By only enabling the protocols that your computer can use, the operating

system does not attempt to connect by using protocols it cannot use, and returns status

information to you more efficiently.



To enable or disable a network protocol or component


2. Right-click the connection for which you want to enable or disable a network protocol or

component, and then click Properties.




If this is a local area connection, on the General tab, in This connection uses the

following items, select the check box next to the component you want to enable it,

or clear the check box to disable it.

If this is a dial-up or VPN connection, on the Networking tab, in This connection

uses the following items, select the check box next to the component you want to

enable it, or clear the check box to disable it.

If this is an incoming connection, on the Networking tab, in Network components,

select the check box next to the component you want to enable it, or clear the check

box to disable it.


If you no longer need a protocol or component on any of your connections, you can uninstall

the protocol or component completely. For more information, see Remove a Network Protocol

or Component.

93









You can use this procedure to remove a network component that you no longer need.

2. Right-click the connection from which you want to remove a network component, and

then click Properties.




If this is a local area connection, on the General tab, in This connection uses the

following items, click the client, service, or protocol you want to remove, and then

click Uninstall.

If this is a dial-up or VPN connection, or broadband connection, on the Networking

tab, in This connection uses the following items, click the client, service, or

protocol you want to remove, and then click Uninstall.

If this is an incoming connection, on the Networking tab, in Network components,

click the client, service, or protocol you want to remove, and then click Uninstall.

5. In the Uninstall component name dialog box, click Yes.


Removing a network protocol or component uninstalls it from your computer, and no network

connections have access to that functionality. If you want to remove a protocol or component

94

from only one of your network connections, see Enable or Disable a Network Protocol or

Component.









You can use this procedure to change the order in which network protocols are attempted when

trying to establish communications with a remote computer. This can provide improved

performance when you have multiple protocols installed and your network primarily uses one. If

you set a protocol at the top of the list, it will be tried first. If another protocol is tried first for every

packet, many will fail, and the other protocols will not be tried until that failure occurs.



To modify the protocol bindings order


2. Press ALT to display the menu bar, and then on the Advanced menu, click Advanced

Settings.



4. On the Adapters and Bindings tab, in the Connections list, click the connection that

you want to modify. If you wish to change the order in which your connections are tried,

click the up or down arrow buttons to rearrange the order.

5. In the Binding for ConnectionName list, click the protocol that you want to move up or

down in the list, and then click the up or down arrow buttons to rearrange the order of the

protocols.

95


Network performance can be seriously degraded if you rearrange the bindings order in an

inappropriate way for your network. Set the connections and the protocols that you use to

reach your resources listed first, with less frequently used connections and protocols listed

second.

For example, if you are on a LAN using primarily IPv4, then it is recommended that the LAN

adapter be the first connection listed, and that IPv4 be the first protocol listed for that

connection.









You can use this procedure to change the order in which network providers are accessed when

communicating with the network.



To modify the network provider order


2. Press ALT to display the menu bar, and then on the Advanced menu, click Advanced

Settings.



4. On the Provider Order tab, in the Network Providers list, select the provider that you

want to move up or down in the list, and then click the up or down arrow buttons to

rearrange the order.

96


Network performance can be seriously degraded if you rearrange the provider order in an

inappropriate way for your network. Set the providers that you use most frequently listed first,

with less frequently used providers listed second.









You can use this procedure to select the name service provider and network address for the

Remote Procedure Call (RPC) service.

You can use this procedure to enable or disable the Negotiate multi-link for single-link

connections option for your remote access connections.

This option enables separation of high and low-priority channels over a single link connection. If

your remote access server supports this feature, you might notice improved audio quality.

However, because this feature is incompatible with many remote access servers, you should

leave it disabled unless instructed otherwise by the administrator of the remote access server.


To enable or disable multilink for single-link connections





5. Select or clear the Negotiate multi-link for single-link connections check box.





This section documents procedures to secure the data you transmit from your computer to the

other computers and networks to which you are attached.

Whenever you connect your computer to another computer or to a network, you risk exposing

your computer to several threats. Some of the common threats, such as malware (viruses,

spyware or other malicious software) are addressed by using antivirus and anti-spyware

programs.

101

In addition, the data you send and receive over the network can potentially be intercepted and

examined. To protect the confidentiality of your data, you can configure identity authentication and

data encryption for the traffic and data of your network sessions.

You can use this procedure to configure smart card or other certificate-based authentication.

Smart card and certificate authentication are considered to be more secure than the traditional

combination of a user name and password. Knowledge of the user name and password is

inadequate, and you must have access to the smart card or certificate in order to complete the

connection. Certificates, including those embedded in a smart card, are encrypted and can be

validated against a trusted certification authority.

Check with the administrator of the remote host to which you want to connect for the security

options supported by that computer.


To enable smart card or other certificate authentication


2. Right-click the dial-up, virtual private network (VPN), or broadband (PPPoE) connection

on which you want to use smart card or other certificate authentication, and then click

Properties.

3. If you are using typical settings for your smart card, on the Security tab, click Typical

(recommended settings), and in the Validate my identity as follows list, click Use

smart card, and then click OK.

4. If you are individually enabling, configuring, and disabling authentication methods and

encryption requirements, on the Security tab, click Advanced (custom settings), and

then click Settings.

5. In Logon security, click Use Extensible Authentication Protocol (EAP), select Smart

card or other certificate (encryption enabled) from the list, click Properties, and then

do the following:

If you want to use the certificate on your smart card, click Use my smart card.

104

If you want to use the certificate in the certificate store on your computer, click Use a

certificate on this computer.

If you want to verify that the server certificate presented to your computer has not

expired, has the correct signature, and has a trusted root certification authority, select

the Validate server certificate check box.

If you only want to connect to specific servers, select the Connect to these servers,

and then type the name of the servers.

If you want to specify that the root certification authority for your server certificate

must be in a particular root certification authority, in Trusted root certification

authority, click the appropriate certification authority.

If you want to use a different user name when the user name in the smart card or

certificate is not the same as the user name in the domain that you are logging on to,

select the Use a different user name for the connection check box.


If, for example, you work for a consulting company where you need to log on to the domain of

the company to which you are assigned, but your smart card contains a user name specific to

your home company, select the Use a different user name for the connection check box.

If you select the Use a different user name for the connection check box, your certificate is

exported without private keys and submitted to the administrator of your remote server to be

explicitly mapped to your domain user account.

Install a Modem

To install the modem hardware on your computer, refer to the manufacturer's documentation.

Generally, the following instructions apply:

If you have an older, internal modem with jumpers, set the jumpers for Plug and Play.

If you have an external modem, ensure that it is attached to the computer, plugged into the

power source, and turned on before you turn on the computer and start Windows.

Ensure that your modem is properly connected to the phone line and to your computer.

109

Most modems manufactured now are compatible with Plug and Play and installed automatically

after they are connected to the computer. However, older modems and external serial modems

might not be detected. If your modem is not installed automatically, then use the procedure below

to install it manually. To choose the modem type manually, see Install an Unsupported Modem.

Options.

2. If you are prompted for dialing location information, enter dialing information for your

location, and then click OK.

3. On the Modems tab, click Add.



5. Follow the instructions in the Install New Modem page.


A standard user can install and use a modem if the driver for the modem is included with

Windows, or if the driver has been staged on the computer by an administrator. Otherwise,

you must have administrative privileges to install a device driver that is not included with

Windows. For more information about staging device drivers, see "Step-by-Step Guide to

Device Driver Signing and Staging" on the Microsoft Web site

(http://go.microsoft.com/fwlink/?linkid=69208).

If the Install New Modem page does not detect your modem or you cannot find it listed, see

Install an Unsupported Modem.

If you are installing an external modem and a cable is not provided, refer to the

manufacturer's instructions for cabling requirements. Most common cables will work, but

some cables do not have all the pins connected. Do not use the 9-to-25 pin converters that

You can use this procedure to enable or disable network discovery, file sharing, or printer sharing.

Network discovery enables a set of Windows Firewall rules that allow your computer to be found

by other computers on the network. When network discovery is turned off, Windows Firewall

prevents your computer from responding to network discovery protocol traffic.

File sharing and printer sharing can be controlled at different levels:

130

File sharing. When this is turned on, Windows Firewall allows standard users to choose

whether to share files or folders in their profiles, that is, files and folders under %systemroot

%\Users\%username%. Administrators can share any file or folder on the computer.

Public folder sharing. Turning this on automatically shares the folder found at %systemroot

%\Users\Public. Turning on public folder sharing automatically turns on file sharing, which is

required.

Printer sharing. Turning this on shares the printers which are installed on this computer so

they can be used from other computers on the network. Selecting the Printer Sharing option

automatically selects the File Sharing option, which is required.

Password protected sharing. This option is available on computers that are not joined to a

domain. Turning this option on restricts access to shared resources to only those users that

have valid user accounts and passwords on this computer. To grant access to a shared folder

on this computer to a user on another computer, you must create a user name and password

on this computer and supply them to the other user for use when accessing this shared

folder.

Media sharing. Turning this on enables sharing files found in your Windows Media Player

Library. Media sharing uses different protocols and Windows Firewall settings, and can be

enabled without having to enable File Sharing.



Enabling Sharing and DiscoveryYou can use the following procedures to enable sharing and network discovery:

To enable network discovery

To enable file sharing or printer sharing

To enable public folder sharing

To enable password protected sharing

To enable media sharing

By default, sharing and network discovery are not enabled.

Enable network discovery

131

network discovery.

4. To prevent your computer from being found by other computers on the network, click

Turn off network discovery.

5. Click Apply.




To use the Ping tool you must enable File Sharing. Turning on Network Discovery does not

enable the ports used by Internet Control Message Protocol (ICMP), the protocol used by

Ping.

If you have firewall software installed, it can affect your ability to use Ping or other diagnostic

networking tools. To use Ping, ensure that your firewall software is configured to allow ICMP

protocol packets.

Enable file sharing or printer sharing

To enable file sharing or printer sharing


2. Click the down arrow button next to either File Sharing or Printer Sharing.

3. To allow users to share files or folders, or to share printers, click Turn on file sharing or

Turn on printer sharing.

4. Click Apply.




Firewall software blocks network sharing by default for security. To use file sharing or printer

sharing in Windows, you must ensure that your firewall software is configured to allow the

appropriate networking protocols to communicate. Consult the documentation that came with

your firewall software.

Turning on printer sharing automatically turns on file sharing, because printer sharing uses

the same protocols as file sharing, and requires the same Windows Firewall rules to be

enabled. However, the reverse is not true: turning on file sharing will not automatically turn on

printer sharing.

To allow some users to share files, but prevent others, see Enable or Disable File Sharing for

a User or Group by Using Group Policy.

rules than file sharing. Turning on File Sharing is not required.

134

Make sure to turn on network discovery, or else other devices on your network cannot find

your computer in the Sharing Settings list of devices.













You can use this procedure to customize the way a network is displayed in the Network and

Sharing Center for standard users.

When Windows detects a new network, it is displayed in the Network and Sharing Center by

using the Domain Name System (DNS) domain name associated with that network. A default icon

appears, based on the selection of public, private, or domain network that is assigned to the

network. You can change the displayed name to something more recognizable to the user on the

computer, such as "Contoso Corporate Network" rather than the default of something similar to

"corp.contoso.com". You can also change the icon that appears.

If the network is not associated with a domain, then you can also choose between private and

public network location types.

Caution

Your selection of a network location type has security implications that you must

understand. Selecting the private network location type allows more network services to

operate than are appropriate on a public network. Ensure that you select the network

location type appropriate for your network.

135



To customize the appearance of a network in the Network and Sharing Center


2. On the right-hand edge of the window, click Customize next to the network you want to

change.

3. In the Network name text box, enter the display text you want Windows to use to identify

your network.

4. In the Location type section, select either Public or Private. This option is only available

if the computer is not a member of a domain on this network.

5. Click Change to select an icon, or to choose a custom icon to represent your network.

6. If Windows has created multiple network locations for a network that you want treated as

a single network, you can click Merge or delete network locations to consolidate them,

or to delete locations you no longer need.

Administrators can configure specific features of how the Network and Sharing Center work in a

managed network environment.

Most of the procedures in this section use Group Policy. If you edit policy settings locally on a

computer, you will affect the settings on only that one computer. If you configure the settings in a

Group Policy object (GPO) hosted in an Active Directory domain, then the settings apply to all

computers that are subject to that GPO. For more information about Group Policy in an

Active Directory domain, see Group Policy (http://go.microsoft.com/fwlink/?LinkId=55625).

This section includes the following tasks for administering the Network and Sharing Center:

Configure Network Connection Restrictions by Using Group Policy

Use the Network Configuration Operators Group

Configuring the Network Map

Enable or Disable Internet Connection Sharing by Using Group Policy

Enable or Disable the Network Bridge by Using Group Policy

Enable or Disable File Sharing for a User or Group by Using Group Policy





Configure Network Connection Restrictions by Using Group Policy

You can use this procedure to configure some restrictions on network connections by using

Group Policy. These settings are all found in the Group Policy Management Console (GPMC)

under:

141


User Configuration\Administrative Templates\Network\Network Connections

Most of the Group Policy settings in this section of the Group Policy Management Console are

only applicable to users using computers running previous versions of Windows, and do not have

any effect on users using computers running Microsoft™ Windows Vista® or

Windows Server® 2008. However, the following Group Policy settings can be edited and applied

to users that are members of the Group Policy object (GPO) in which the Group Policy setting is

included. By default, the Group Policy settings are not configured.

The Group Policy settings that affect users of Windows Vista and Windows Server 2008 include:

Prohibit deletion of remote access connections. If you enable this Group Policy setting,

then affected users cannot delete any remote access connections, including those they

create themselves.

Prohibit access to the Remote Access Preferences item on the Advanced menu. If you

enable this Group Policy setting, then affected users cannot access the Remote Access

Preferences setting on the Advanced menu of the Network Connections folder. The top

menu bar, including the Advanced menu, appears when you press the ALT key.

Prohibit access to properties of a LAN connection. If you enable this Group Policy setting,

then affected users cannot change any of the properties of a LAN connection.

Ability to change properties of an all user remote access connection. If you enable this

Group Policy setting, then affected users can modify the properties of a remote access

connection that is shared with the other users on the computer. By default, standard users

can only modify properties for a connection that is not shared.

Prohibit connecting and disconnecting a remote access connection. If you enable this

Group Policy setting, then affected users cannot connect by using any remote access

connection, or disconnect any that are currently connected.

Prohibit changing properties of a private remote access connection. If you enable this

Group Policy setting, then affected users cannot change the remote access connection

properties that are not shared. By default, standard users can modify connections that are not

shared.

Prohibit renaming private remote access connections. If you enable this Group Policy

setting, then affected users cannot rename remote access connections that are not

shared. By default, standard users can modify connections that are not shared.



To open the Group Policy Management Console as an administrator

1. Click Start, then in the Start Search box, type gpmc.msc, but do not press ENTER.

2. When the icon for GPMC.msc appears on the Programs list at the top of the Start menu,

right-click it, and then click Run as administrator.

142

If the User Account Control dialog box appears, ensure it is for the action you

requested, and then enter your administrator credentials.

If you edit policy settings locally on a computer, you will affect the settings on only that

one computer. If you configure the settings in a Group Policy object (GPO) hosted in an

Active Directory domain, then the settings apply to all computers that are subject to that

GPO. For more information about Group Policy in an Active Directory domain, see Group

Policy (http://go.microsoft.com/fwlink/?LinkId=55625).

To enable or disable a Network Connections restriction policy for the current user

1. Log on as the user for which you want to apply these Group Policy settings.

You can use this procedure to delegate the ability to manage most aspects of a computer's

network connectivity.

Many configuration restrictions that used to be applied by using Group Policy in earlier versions of

Windows are now restricted. To create a connection that is shared by multiple users, or to make

any configuration change that impacts a connection used by multiple users requires membership

in either the Administrators or Network Configuration Operators group. A standard user can create

new network connections, but can only save those connections for his or her own use. If you want

to allow someone to perform the configuration tasks documented in this guide but not make them

an Administrator, then you can make the user a member of the Network Configuration Operators

group.



To delegate network configuration permissions to a user

1. Start Computer Management by clicking Start, right-clicking Computer, and then clicking

Manage.

2. In the navigation pane, navigate to Computer Management (Local)/Local Users and

Groups/Groups.

3. In the details pane, double-click the Network Configuration Operators group.

4. Click the Add button, and then select the users or groups to whom you want to delegate

permissions.


Not all tasks in this guide can be performed by a member of the Network Configuration

Operators group. Check each procedure for information about what group membership is

required. If a procedure only indicates that Administrators can perform the task, then a

member of the Network Configuration Operator group receives an error when trying to

perform that task.

If a member of the Network Configuration Operators group attempts to perform an action that

cannot be performed by a standard user, then the User Account Control dialog box appears.

This dialog box presents user accounts that can perform the operation. Clicking a user name

on the list and entering its password allows the operation to proceed by using those

credentials. If the user's current account that is a member of the Network Configuration

Operators group is not displayed, then that group cannot perform that operation.

144

Administrators can choose to enable or disable the Network Map feature in Windows. Network

Map uses two components:

The Mapper input/output (I/O) component queries the network for devices to include in the

map.

The Responder component runs on computers on the network, and allows them to respond to

the queries from the Mapper I/O.

Group Policy settings supported in Microsoft® Windows Vista® and Windows Server® 2008

enable an administrator to enable or disable Network Map components in any of the three

network types: Public, private, and domain. By default, the components run on private networks,

but do not run on a domain or public network.

You can install a Responder component on computers running Windows XP so that they will

appear on a Network Map. The Group Policy setting for the Responder component on

Windows XP only controls whether or not the Responder can run in a domain environment.

Windows XP does not recognize public and private networks in the same way as Windows Vista

or Windows Server 2008.

Enable or Disable the LLTD Responder by Using Group Policy

You can use this procedure to enable or disable the Link Layer Topology Discovery (LLTD)

Responder component, and specify the network location types in which it is allowed to run.

The LLTD Responder component is a network component that allows the computer to be

discovered by another computer running the Network Map feature. For more information about

the Network Map, see Display the Network Map.

By default, the responder only runs on a network that is designated private, but does not run on

networks that are designated public or domain. By using Group Policy, you can disable the

responder altogether, or change the location types in which it is allowed to run.



To enable or disable the LLTD Responder by using Group Policy

1. Start Group Policy Management Console (GPMC). To do so, click Start, and then in the

Start Search box, type gpmc.msc.

2. In the navigation pane, open the following folders: Local Computer Policy, Computer

Configuration, Administrative Templates, Network, and Link-Layer Topology

Discovery.

3. In the details pane, double-click Turn on Responder (RSPNDR) driver.

4. To disable the responder component completely, click Disabled, and then click OK.

5. To enable the responder component, click Enabled, and then select one or more of the

following:

Allow operation while in domain

Allow operation while in public network

Prohibit operation while in private network



The LLTD Responder component is included with Microsoft® Windows Vista® and

Windows Server® 2008. A version of the LLTP Responder component for Windows XP can

be downloaded at http://go.microsoft.com/fwlink/?LinkId=70582 on the Microsoft Web site.

146


If you edit policy settings locally on a computer, you will affect the settings on only that one

computer. If you configure the settings in a Group Policy object (GPO) hosted in an

Active Directory domain, then the settings apply to all computers that are subject to that GPO.

For more information about Group Policy in an Active Directory domain, see Group Policy

(http://go.microsoft.com/fwlink/?LinkId=55625).

A separate component, the LLTD Mapper I/O, runs on the computer that is generating the

map and communicates with the computers running the Responder component. To configure

the Mapper I/O component, see Enable or Disable the LLTD Mapper I/O by Using Group

Policy.

Changing a Group Policy setting does not always immediately put the changed setting into

effect. To ensure that the Group Policy setting is applied, either restart the computer, or run

gpupdate /force at a command prompt.

See AlsoEnable or Disable the LLTD Mapper I/O by Using Group Policy



You can use this procedure to enable or disable the Link Layer Topology Discovery (LLTD)

Mapper input/output (I/O) component, and specify the network location types in which it is allowed

to run.

The LLTD Mapper I/O is a network component that discovers and communicates with the LLTD

Responder component running on other computers on your network. The information discovered

by the Mapper I/O allows the Network Map feature to diagram the devices on and connectivity of

your local subnet. For more information about the Network Map, see Display the Network Map.

By default, the Mapper I/O component only runs on a network that is designated private, and

does not run on networks that are designated public or domain. By using Group Policy you can

disable the Mapper I/O component, or change the location types in which it is allowed to run.



To enable or disable the LLTD Mapper I/O by using Group Policy

You can use this procedure to enable or disable Internet Connection Sharing (ICS).

ICS allows a computer that is connected to both a private and public network to share access to

the public network with all computers on the private network. In an enterprise environment where

you want to control access to the public network, you can disable ICS on all other computers to

reduce the risk of unmanaged access to the public network.

If you disable ICS on a computer, the following results occur:

The ICS service cannot be started or configured.

The Advanced tab in the Connection Properties dialog box is removed.

The Internet Connection Sharing page is removed from the New Connection page.

The Network Setup page is disabled.



To enable or disable Internet Connection Sharing

1. Start Group Policy Object Editor. To do so, click Start, and then in the Start Search box,

type mmc gpedit.msc.


149


Configuration, Administrative Templates, Network, and Network Connections.

DNS domain network.


To enable the Group Policy setting, and disable ICS, click Enabled.

To disable the Group Policy setting, and enable ICS, click Disabled.



If you move the computer to a different Domain Name System (DNS) domain after applying

or refreshing the Group Policy setting, the change will not take effect until the Group Policy

setting is refreshed again.












You can use this procedure to enable or disable the user's ability to install and configure a

network bridge.

The Network Bridge setting, if enabled, allows users to create a Layer 2 Media Access Control

(MAC) bridge, enabling them to connect two or more physical network segments together. A

network bridge thus allows a computer that has connections to two different networks to share

data between those networks.

150


In an enterprise environment, where there is a need to control network traffic to only authorized

paths, you can disable the Network Bridge setting on a computer. If you disable Network

Bridge on a computer, users cannot create or configure a network bridge. By default, this setting

is not configured.



To enable or disable Network Bridge




Configuration, Administrative Templates, Network, and Network Connections.

This setting is location-aware. It only applies when a computer is connected to the same

Domain Name System (DNS) domain network it was connected to when the setting was

refreshed on that computer. If a computer is connected to a DNS domain network other

than the one it was connected to when the setting was refreshed, this setting does not

apply

3. In the details pane, double-click Prohibit installation and configuration of Network

Bridge on your DNS domain network.


To enable the Group Policy setting, and disable the Network Bridge setting, click

Enabled.

To disable the Group Policy setting, and enable the Network Bridge setting, click

You can use this procedure to install additional network features, such as network-aware

applications and services that are not installed by default.

For security reasons, specific network features included with Windows are not installed by

default. Install these features only if you need to use them, because they open additional network

ports through the firewall, and increase the exposure of your computer to others on the network.

The additional network features available include:

Internet Information Services (IIS), which includes a Web and FTP server

LPD and LPR Print services for printing to and from UNIX-based computers

RIP Listener, which supports Routing Information Protocol version 1

Services for NFS, which supports file sharing to and from UNIX-based computers

Simple TCP/IP services, which provide miscellaneous network features
