I’ve had this problem twice now. I built an SBS 2000 (Small Business Server) by installing SBS in a new directory on an NT4 PDC. (I now have the option to duel boot) I removed a w2k workstation from the NT4 domain by using Server Manager, and, putit in a workgroup at the workstation. Now, I boot the server as SBS, and try to join the domain with that workstation, but I’m not able to. The error message says the domain does not exist or cannot be contacted. The strange part is, the workstation will reply to pings from the server, but the server will not reply to pings from the workstation. When I go back to NT4, the workstation can again join that domain, and the pings reply in both directions. The first time this happened, the server was a clean install, not a duel boot. But it was built at another location, then relocated. I rebuilt that server from scratch to resolve that problem, but I’m not sure what I might have done differently durring the second rebuild.
The only common factor I can think of in the two cases where it didn’t work is, while installing SBS I answered the question concerning the domain name for PRE2000 machines with the same name as the NT4 domain. But again, neither was a domain upgrade, and that doesn’t explain why the server doesn’t reply to pings.
Anyone have any ideas? Thanks
