We have a new windows 2012 clustered server which was built and named the same as a previous 2008 R2 cluster. It is not a terminal server... just a SQL 2012 Server. When I try to RDP to it, I get a message that "the connection cannot be completed because the remote computer that was reached is not the one you specified."
Forward and reverse dns looks fine. You can flush the dns cache and it still happens. But you can get to it by going straight to the IP.
