I'm getting a really intermittent error (once or twice a week) when connecting via RDP onto a windows server 2012 terminal server (DC is running SBS2011).
Upon connection the error message "the specified domain could not be contacted or does not exist" appears.
To reiterate, this only happens very occasionally and by logging on to the servers local profile, remotely, then restarting the machine it will be working fine again.
Thought it would be a DNS issue and sure enough when I checked there were two pointers in DNS on the DC, one for the terminal servers current IP address and one for and old IP that wasn't being used anymore. Deleted the unneeded pointer and thought the problem was fixed for a while but its come back to haunt me again!
Any ideas folks?
