Great fix for a problem I commonly have at the office:
If you’ve worked on a network with Windows servers, you’ve encountered this error message at least 37,000 times:
“The terminal server has exceeded the maximum number of allowed connections. The system can not log you on. The system has reached its licensed logon limit. Please try again later.”
This problem happens because Windows only allows two remote terminal services connections when you are in administrative mode, and you’ve either got two people already on that server, or more likely, you’ve got a disconnected session that still thinks it is active.
The problem with this error is that you have to actually get on the server console to fix the problem if the server isn’t in a domain. (If you are in a domain, then just open Terminal Services Manager and log off or disconnect the sessions)
