Issue:
I cannot connect after the Windows update to a server with a Thinstuff XP/VS Server (Multi-session remote desktop server) terminal solution.
When trying to connect I get the following error message:

"The number of connections to this computer is limited and all connections are in use right now."

Solution:

This issue is caused by using a Windows security update, as Microsoft makes changes, which interrupts Thinstuff XP/VS Server terminal connections.

• Update XP/VS Server
• Restart server
• Check if Thinstuff service is started
• Check if the imported license is valid

Always check an official Thinstuff changelog to see if your service has a new update.
