We are running SBS 2003 with Terminal Services. On a few of the clients we get a message something like "A security error has occured, unable to connect to client services." If you click ok it goes away, click connect again and you go right in if your local, you don't get in at all if your remote. We had a problem occur when the temporary licensing ran out as we thought we had it configured properly to pull licensing from another server. The licenses are all in place, latest service pack is loaded but this problem still exist (the service pack cleared up the other one we were having.) Any suggestions would be appreciated.
