I recently migrated all the domain controllers in a multi site environment to Server 2016. In one of the sites one domain controller shows its name with some kind of a code (I believe its SID). Now it doesn't allow me to transfer fsmo roles to new server using the new server name (STWN-AD03), See attached. In sits and services and /replsummary also shows the server name with same name.
I hope you can help me find what caused it. Like I mentioned this domain has 3 sites and changes replicated throughout all sites.
I was thinking replication delays might have caused it while I'm upgrading, because after upgrading Site A, I didn't check all changes are replicated to other 2 sites before moving on to Site B. Any thoughts?
How can I fix this? I there any way without going for a fresh server? (because we already migrated a payroll application to the new server)
