Have a 2003 server which was an AD server and was demoted and was still a member of the domain. After some time, was unable to login to the domain, so have been logging in locally. For some reason, the server cannot see the rest of the domain. DNS on this server wasnt pointed to itself and had since been corrected. (does a DNS server have to be an AD controller?- does this have to "propogate"?) I saw somewhere with a similar problem that it should be unjoined and rejoined, however, get this error, that the "user already exists". I am assuming its not the "user" but the computer name in AD. so I located it in AD and deleted it. Then went to re-join, and rec'd the same error. Is there anywhere else I need to delete or tell the system / AD this server is no longer part of the domain so it can rejoin? Am I missing something else?
