Purpose of CoursePurpose of Course
To become a successful Technical Project Manager, one must have an understanding of how your E-Commerce affects various components in the corporate environment.
One of the areas that you will most impact is the Networking Department(s) within that organization. These areas support and maintain the systems you create and oversee.
You are their customer; but, your success is heavily dependent on them.
So???So???
Throughout this quarter, we will be looking at the Management of a Corporate Network environment.

What is a Network?What is a Network?
A grouping of computer nodes that are interconnected for the purpose of
data communication.
Computer networks are supposed to increase efficiencies so that resources
can be focused on core business functions.
Why do we Need a Computer Network?Why do we Need a Computer Network?
How do we effectively set up and run a How do we effectively set up and run a network?network?
• We will be using Windows 2000 as the test O/S for network administration in this class
• Prior knowledge of NT or 2000 will not be required, but will help you– IT students will get to refresh– Electronics students will become
exposed to concepts in networking
Please ask questions!
Overview of DHCPOverview of DHCP
• Manual vs. Automatic TCP/IP Configuration
• DHCP Operation
• The DHCP Lease Generation Process
• The DHCP Lease Renewal Process
• Requirements for DHCP Servers and Clients
What is DHCP?What is DHCP?• Dynamic Host Configuration Protocol
• DHCP assigns an IP address to the host when user logs in. IP address is like postal address. Allows one to access information in network, similar to a key. Based upon your key, you have access to particular files, printers - whether you will merely use them, manage them, or not even see them
Manual vs. Automatic TCP/IP Manual vs. Automatic TCP/IP ConfigurationConfiguration
Disadvantages
Manual TCP/IP ConfigurationManual TCP/IP ConfigurationManual TCP/IP ConfigurationManual TCP/IP Configuration Automatic TCP/IP ConfigurationAutomatic TCP/IP ConfigurationAutomatic TCP/IP ConfigurationAutomatic TCP/IP Configuration
Advantages
IP addresses entered manually on each client computer
Possibility of entering incorrect or invalid IP address
Incorrect configuration can lead to communication and network problems
Administrative overload on networks where computers are frequently moved
IP addresses are supplied automatically to client computers
Ensures that clients always use correct configuration information
Elimination of common source of network problems
Client configuration updated automatically to reflect changes in network structure
