I have 4 servers all running Win2k and Terminal Service in Admin Mode. 2 will connect just fine (they were clean installs) 2 will not connect with the message Terminal Server has ended the connection. The 2 that will not connect were upgraded from Win NT 4.0 Server. One has SP4 and one has SP3. I have check and tried all the KB articles I could find on TS but nothing is resolving the problem. Again it is only on the TS that were upgraded. Anyone have a thought?
