Have an NT4 Server machine that every time I try to join our domain I get " no domain controller can be found" I am trying to join the correct domain. The IP addresses, Dns addresses, wins server addresses, gateway and protocals are correct. I can ping any machine on our domain by name or by IP. I can pcanywhere into this machine from machines on our domain. I can ping machines outside in the real world. I am logged into the machine as local admin and am on just a workgroup that has only this machine on it. I am at a loss?? We put machines on the domain here every day with no issues, I assume it is a software issue on this server.

It's a wins issue. Make sure this server has the correct wins ip addresses in tcp/ip properties and the wins database has the correct entries. Make sure its up on service pack 6a

I am pretty confident that the wins and backup wins servers are correct. And it is resolving because I can ping all the computers on the domain by computer name from this machine. Service pack 6a I think is on the machine but definatly will check that to make sure. I know it is some stupid little thing that has happend to the NT4 install..

Well that's a stumper. I recently have worked on the very same issue with this error message on my system. Knowledge base articles pointed to wins/dns. Fixed and alls well. This server has no account on the pdc yet right? You should get a different error if this was the case but I have found OS's less then reliable in posting what the real problem is. Sometimes you have to read between the lines to get the true issue. I would look at things like route print, nbtstat -A serveripaddress, arp ... You don't have a lmhosts file on here do you? I am thinking something is telling the join the domain function the wrong location.
