I want to retire the server that has my primary DNS and Active Directory Domain Controllers on it. It is a 2012 R2 and I have 2 others with DNS and are Active directory Domain Controllers. I ran the command nltest /dclist:domainname.local and it find all3 domain controllers with the one I want to retire listed with PDC. I can't find a way to promote one of the other domain controllers to the primary. How do I do that. I don't want to remove the Primary until I have promoted on of the others.
Also is there anything I need to do with the DNS servers. The one I want to retire was created when the Active Directory role was installed.
