3 years ago I upgraded an NT4 machine to Server 2003 and created a new domain. I then added 2 brand new server 2003 DCs, DC1 and DC2 and moved all roles and everything. I then powered down the original machine.
The original machine is still in AD as a DC. I would like to remove it completely in the best possible way. When I power it on and try DCPROMO it says it cannot contact the DC and something about an invalid account.
Do I have to do a force remove dcpromo or is there another way?
NOTE - This DC is not crashed and is a virtual machine so I can bring it up any time.
