I need to delete an otherwise "non removable" domain controller box that runs windows server 2003.
Normally I use
dcpromo to remove domain controller roles from active domain servers. I tried to do that with our last Windows Server 2003 level server, but it keeps failing with errors. So I have decided to try to remove this domain controller using the Windows Server 2012 primary domain controller.
There is a tool new to 2012 server called Active Directory Administrative Center, but it has this delete option grayed out:
First, does anyone know why and if this can be fixed somehow, and if not (and if the reason is because the domain is still at the 2003 functional level), how do I get out of this catch-22 situation? I can't upgrade the domain functional level until I remove the last windows server 2003 server, and
dcpromo doesn't work (it fails to remove ActiveDirectory services from the server, and just exits out with some kind of communication error).
The old tools I know how to use appear to be gone from 2012, and the new friendly tool (ADAC) appears useless and crippled. I'm guessing it's back to the command line for cleaning up this particular mess.
