We have network which currently has a windows 2008 standard server as our domain controller. We also have a new Windows 2012 standard server, running hyperv, which we have also installed active directory.
We would like to migrate the fsmo roles to the new server.
We firstly wanted to raise the functional level of the dc to 2012 standard, but find that we are advised that :-
To update the domain functional level, the Active Directory Domain Controllers in the domain must be running the appropriate version of windows.
Current domain functional level
Windows Server 2003
The following Active Directory Domain Controllers are running earlier versions of windows:
domain Name AD DC Version of Windows
domain.local server1.domain.local Windows Server 2003 5.2 (3790)
This windows 2003 standard server was on the far side of a wan, and is no longer in operation. ie it does notexist any more.
I dont know how this was removed, but I can confirm that it is still listed under "domain controllers" in our active directory.
What would be the best way of clearing this down, so that we can raise our functional level prior to moving the fsmo roles.
Any assistance would be very much appreciated.
