I have a TS-RVHl920 using NT Domain authentication to a Windows 2003 SBS server.
We are upgrading our Server and environment to Windows 2012 R2.
I tried changing the NT controller name in the NT environment to the new server name and also changing to Active Directory but each time get a Fail to join the domain error.
Do I need to leave the domain and rejoin or is there a way to simple point to a new Server ?
