We are planning a NT 4.0 to AD Migration. I implemented Windows 2000 DNS, WINS, and DHCP to prepare. Clients are using default config, but will not update their host record in DNS. Pre-W2K clients register in DHCP as client1.mydomain.com, and update a record in DNS. W2K clients register as client1 in DHCP, and will not update DNS. Some 2000 Servers with static IP addresses automatically update their DNS record, but not all of them. The check box on the client is check to register in DNS. What am I missing?
