W2K domain controller has wrong FQDN

Hello,

I have a domain (DOMAIN1) with 4 Windows domain controllers. One is Windows 2003/Exchange and the others are Windows 2000 file servers.

I need to demote one of the w2k servers and remove it permanently from AD. The problem I'm having is that it is a member of DOMAIN1 but the actual name of the server is "server.DOMAIN2.com". How this happened, I don't know, but it seems to be causing problems where this server cannot replicate with the others.
I cannot run dcpromo successfully on this DC or rename it in its present state. Should I force demotion on this server and  then run ntdsutil on the other DCs to clean them up?  Is there a way I can play with my DNS settings to get this thing to replicate properly?

Can anyone suggest a solution to this problem?

Thanks very much!

Is everything except that server replicating properly? You've tried DCDiag and such?

If so, I'd go with turning it off then cleaning it up afterwards (with NTDSUtil as you suggest). Then I'd strongly recommend you rebuild the system completely.

Check against your DNS record first. The name may probablly mistyped. After force removal of that w2k DC. try to delete the DC inside dsa.msc as well. and Check the DC cannot be contacted and permenta offline option. After that, run site and services and try to replicate to all other DC. GOod Luck

Thanks guys. When I force replication, the other 3 DC are replicating okay against the bad one. The bad one however is not replicating against the other three. I'm going to force demotion sometime in the next few days. I'll let you know how it turns out.
