This is a one horse shop, 2 servers, both domain controllers. Named: mail and company1 (name changed to protect the innocent)
By Mistake, I built a new desktop and without thinking, wanting to use something generic, chose the name of one of the domain controllers. I realized the mistake right away as it said there exists a duplicate name on the network. I changed it right away, but now I"m getting kerberos erros when replicating to the domain controller. Checking AD, the DC stayed in the same OU, but was removed from the domain controllers group, and placed in the domain computers group. I'm starting to see errors across the network with authentication. I think most have been authenticating on this particular server. The MS article said to remove all duplicate names, which have been done. I have changed group membership of the DC and returned it to domain controllers, and removed it from domain computers. But am afraid to reboot lest the server eat itself. Am I safe to reboot? I don't know if it is the global catalog host or not.
