• List the networking services available in Windows Server 2003

3

New Features of Windows 2003• Enhanced Active Directory

– Now more flexible, manageable, and reliable

• .NET Framework– Allows programmers develop applications in a

variety of languages, such as C++, C#, or Visual Basic

• Web services– Native support for XML Web services is included

• Enhanced clustering and load balancing– Maximum cluster size increased from four to eight

nodes

4

New Features of Windows 2003 (Continued)• Automated system recovery

– Allows single step recovery of operating system• Internet Information Server (IIS) 6.0

– Default configuration locked down to be more secure

• Internet Protocol version 6 (IPv6)– The future of Internet connectivity and will replace

the current Internet Protocol version 4 (IPv4)• Point-to-Point Protocol Over Ethernet (PPPOE)

Enhanced IP Security (IPSec)– Used by many high-speed Internet service

providers (ISPs) to control traffic on their networks

5

New Features of Windows 2003 (Continued)

• Network bridging– In smaller networks, Windows Server 2003 can

be used as a bridge

• Wireless support– Includes extensions to Group Policy and a

Microsoft Management Console (MMC) snap in

• Enhanced IP Security (IPSec)– Allows transmission of encrypted packets through

network address translation (NAT)

6

New Features of Windows 2003 (Continued)• Internet Connection Firewall (ICF)

– Basic firewall protection provided for small businesses

• Volume Shadow Copy– Allows files to be backed up when they are open

• Windows Media Services– Can provide streaming audio and video

• 64-bit support– Support for 64-bit processing on Intel Itanium

Processors

7

Web Edition

• A lower-cost version of Windows Server 2003 that is optimized to be a dedicated Web server

• Meant to counter Linux in the market for utility servers

• Some unique features– Must be a member server or stand-alone server

– Load balancing is supported

– Clustering is not supported

– VPN support is limited

– Services for Macintosh are not supported

Windows Server 2003 Network Architecture

• Four major components in networking– Client: makes requests for resources on the

network

– Service: responds to requests from client software and provides access to resources

– Protocol: used by client and service software to communicate

– Adapter: driver for the network card

16

Windows Server 2003 networking architecture

17

Network Device Interface Specification (NDIS)

• A specification created by Microsoft and 3Com to speed the development of device drivers and enhance networking capabilities

• Bindings between protocols and adapters controlled by NDIS

18

Transport Device Interface (TDI)

• Provides clients and services with access to network resources

• Emulates two network access mechanisms:– Network Basic Input Output System (NetBIOS)

– Windows Sockets (WinSock)

• Windows Sockets Direct (WinSock Direct)– New enhancement to WinSock that is used to

access resources on system area networks

19

Network Protocols

• IPv4 – Normally referred to as TCP/IP

• IPv6 – Newer version of TCP/IP that offers a number of

enhancements• Internetwork Packet eXchange/Sequenced

Packet eXchange (IPX/SPX) – Used primarily for backward compatibility with

older networks running Novell Netware• AppleTalk

– Used to communicate with Apple Macintosh computers

20

Networking Services

• Dynamic Host Configuration Protocol (DHCP) – Automated mechanism used to assign IP

addresses to client computers

• Domain Name System (DNS) – Converts host names to IP addresses

• Windows Internet Naming Service (WINS) – Converts NetBIOS names to IP addresses

• Routing and Remote Access Service (RRAS)– Allows Windows Server 2003 to act as a router,

VPN server, and dial-in server

21

Networking Services (Continued)

• Internet Connection Sharing (ICS) – Automated way to set up DHCP, NAT, and a

DNS proxy for small networks• Internet Authentication Service (IAS)

– Allows a company to use Active Directory for centralized authentication of remote access clients

• IP Security (IPSec)– Enhancement to IPv4 that creates secure IP-

based communications

22

Networking Services (Continued)

• Internet Connection Firewall (ICF)– Suitable for small businesses using Windows

Server 2003 as the router connecting to their ISP

• Public Key Infrastructure (PKI)– Certificates can be used to secure e-mail

23
