I am having a BIG problem joining some machines, about 10 of them into a Windows 2012 Server domain. These machines are all fitted with Windows 7 Professional.
The network is flat, both clients and server are on the single switch and they can ping each other. hey, I am even able to ping the domain...but when trying to join the machine to the domain I get the error the "AD domain could not be contacted" (SEE PICTURE ATTACHED).
What could be the problem, and how do I resove this?
