Other Network Considerations

Besides the diagrams of the networks, there are some other things that need to be documented. This will help in your planning by providing you with a baseline to improve on.

Name Resolution Services

Make sure that you document all DNS and WINS servers that are on your network. Make sure the configuration information and version information are included as well as hardware details. If any of the DNS servers are not running Windows NT, check to make sure the version of DNS can support dynamic updates and service (SRV) resource records. If the version of DNS you are using does not currently support dynamic updates, you will have to determine if there are upgrades available from the software.

Most networks are a combination of different operating systems. If the hosts on your network are not running NT, document the services they use and the services they provide, like Unix BIND, Berkeley Internet Name Domain, and DNS. If your network does have BIND present, it may cause a problem because versions earlier than 4.9.7 or BIND 8.1.2 are not compatible with Windows 2000. Other things to note include the presence of Service

Advertising Protocol (SAP) and the Routing Information Protocol (RIP) services.

Before you go into the exam, make sure you know about BIND, RIP, and SAP, and their coexistence in a Windows 2000 environment—not that there would be test questions on this, but you never know!

IP Addressing Configuration Methods

The documentation process should also cover all DHCP service servers on your network, including information like the following:

■ IP addresses that you have statically assigned to servers or client computers

■ DHCP settings, such as default gateways and DHCP relay agents, as well as other DHCP options

■ Subnet details and how they relate to the overall network map

■ The number of subnets and hosts on your network, including a complete list of the IP addresses and subnet masks on the network

■ Lease durations for DHCP addresses

Remote and Dial-Up Networking

Are there remote or mobile users on your network? More documentation! In this case, you have to document how they access the network and what the dial-up configurations look like at various locations. If you use third-party software for mobile users, review and document the configuration of those products. If you use virtual private networks (VPNs), document the configurations of your VPN with the goal of evaluating whether you can replace it with a Windows 2000 VPN.
