I am having a DNS problem that I hope you can help me with. Here is some background information:
We have a Windows 2000 domain that has five domain controllers located throughout Northern Arizona. The domain controllers were named as follows:
a. Arizona - Was our PDC in Windows NT 4.0 environment and also served as our primary DNS server
b. Nevada - Secondary DNS server
The domain controller Arizona was really a semi-beefed up workstation that has Windows 2000 server loaded on it. We decided to replace Arizona with a new domain controller named DC1. We purchased a small server-class machine and loaded Windows 2000 Server on it. We then configured DNS on it and DC Promo to make it a domain controller. Everything up to this point worked as expected. We let DC1 and Arizona co-exist on the domain for two weeks. Last Friday we decided to retire Arizona, so we ran DC Promo on it and made it a member server then turned it off. We then assigned Arizona's old static IP address to DC1, thinking that DC1 would now become our primary DNS server. Apparently this did not work as we are having all sorts of DNS problems. It appears to me that no computers on the network are recognizing DC1 as a DNS server.
Any ideas on how I can correct this problem.
