Problem with demoting a WIN2K Server
Posted on 2003-03-04
We recently upgraded 3 servers from NT4 to WIN2k.
server 1 and 2 went well and were added to active directory, however, server 3 seemed to upgrade and was added to active directory (This server is running Exchange 5.5).
We soon discovered the the server was not replicating, or, the other two servers could not map a drive on the third server.
Funny thing is,any of the Teck support PCs could map to the third server.
Exchange 5.5 is running fine, however we cannot backup the third server at all because the other server can not see the Exchange server.
When you map the third server from server 1 or 2, it states that the remote password is incorrect or sometime it states that name is incorrect.
The problem here is, its active directory, so there is no local username.
I have tried to demote the server, however, that fails with the comment "DSA operations is unable to proceed because of a DNS lookup failure".
I have checked all the DNS entries (_tcp, _ldp, -gc, and so on). I have also checked the WINS, and they are talking to each other.
Server 1 is running DHCP, WINS DNS.
I did notice after all this that the machine name has changed from Servername to Server_name.domain_name, this must have happened during the upgarde.
Does anyone have any idea what going on here.
All comments welcome.
