I have Win2k Pro installed on some laptops in a NT 4.0 domain. All of them are in the workgroup, “Workgroup”. When attempting to add these computers to the domain, I receive the error, ‘domain does not exist or cannot be contacted’ I’m using DHCPwith WINS/DNS/Router. I’m using Windows 4.0 DNS server. I could ping the BDC by name and IP address. But Server Manager on the BDC cannot access these computers. All of these computers’ names have been added manually via Server Manager. I’ve tried LMHOSTS, DNS fixes and static IPs. None of these worked. BDC is multi-homed supporting 2 network IP segments. The other segment(1) is fine (other Win2k installs OK) – this segment has the PDC on it as well. Segment(2) has no PDC, just this BDC. Any suggestions? Thanks.
