I wonder if someone can advise. We have 2 x 2003 AD server on our main site and 3rd one was on a remote site which was used by a sister company. Few months ago they have decided to go solo and contracted their IT to an external company and I was promised that I would be able to demote my 3rd AD before disconnections. Well they have cut all communications and rebuilt that server in the mean time my ADs still thinks that server is connected and of course I could not just delete it. Also I am getting NTDS Replication 1864 error on the PDC and I am not sure how to get rid of this server.
Any help would be appreciate it.
