We've got an aging Windows 2003 server that is only being used for AD and file serving.
As of a week ago all computers on the network no longer see the server as a DC. They can access the files (but need to manually enter credentials) and the server has no problem accessing the network or internet. I wish
I turned off antivirus and firewall but that didn't help. I've also run through the basic ipconfig and dns commands that I know and there is no change. Restarting the server also does not help.
I would appreciate some help in troubleshooting where the problem lies.
