I am currently having difficulties installing a new server into a domain. I have transferred all the roles successfully, but when I shut the old server down the new on takes 20 mins to load and the FQDN has changed from .local to .001 . It is also impossible to access group policy.
When the other server is connected and I access group policy, I get the message that a 'domain controller could not be found', but by choosing the option to use any available controller, I can access the policy.
I promoted the new server to be a GC but am scared to demote the old server even though the replication seems OK using Active Directory Replication Monitor. I am also worried to demote the old server using DCPROMO in case I can't promote it again. These problems have shattered my confidence.
DNS seems OK, and I have tried setting the DNS server on the NIC to both old, then new server with the same results.
Using 'netdom query fsmo' I get confirmation that the roles have gone over.
Any ideas to get a graceful demotion of the old server? Many Thanks.
