Option 1Configure your local DNS server to have the reverse-lookup zone that the Windows 2000-based computers can use to register. For example, if your computers are using a 10.0.0.x IP address, create a reverse-lookup zone of 10.in-addr.arpa on the local DNS server on which the Windows 2000-based computers are attempting to register.
