Replacing old DC problems.
I'm having a very odd problem trying to replace a Old DC with a new one.
On the old server, when entering the new server name at the Change Directory Server screen in ADUC (when trying to transfer the FSMO roles from the old server to the new one), I get the following error:
But if you attempt it from the other way round, ADUC on the new server can change to the old server and back with no problems.
If I then transfer the roles on the new server, the old server reports ERROR for the operation master for all the roles transferred.
Is there something major I've missed out?
Both servers are running 2008R2 Datacenter if this helps?
Thanks in advance!
