Windows 2000 does NOT require that a DNS, or WINS, server use a static IP address, but it is highly recommended.

If the IP address of a DNS or WINS server changes, you can experience client connectivity problems and increased network traffic.

If you manually create a DNS server using the Control Panel applet, you are warned that the DNS service should have a static IP address.

When you use DCpromo to create the DNS server, you are NOT warned when the server uses DHCP to acquire an IP address.
