We just took over a site with two servers an old 2k server and a 2008 r2 machine. Both are setup as Domain Controllers but after running DCDIAG there are all sorts of issues.
The two primary issues are:
The default first site failed advertising
NetLogins is failing on the 2008 server
This domain seems to be a mess. Without setting up a new domain can you offer steps to try and stabilize the domain. We will get ride of the 2k server but need to clean everything up first.
There is also a server listed in the default first site that is not on the domain and must have been removed without going through the proper demotion procedure.
