Hello.

I'm trying to get one of my servers out of my Active Directory scheme as it's going to be retired. It's the second server that we've put in service in the past couple of weeks. However, when I try to demote it using DCPromo, I get a DNS lookup message stating the operation can't continue.

Any thougths?

Is DNS functioning on this server? You can check by pinging by name another DC with the command ping -a XXX.XXX.XXX.XXX where the XXX is the IP address of another server.

Can you still get to Active Directory with Users and Computers from this computer that is having issues being DCpromoed out of the environment?

If all else fails, you can run a metadata cleanup and remove it from AD.

Details of the metadata cleanup are here:

Have a look in your eventlogs for a more detailed description of the DNS lookup message you get. Maybe post the log here.
