If you receive the following message it means you have maxed out the active terminal server connections to the server.
The terminal server has exceeded the maximum number of allowed connections
To get around this, open a Command Prompt and type:
mstsc /v:00.00.00.00 /admin
mstsc /v:00.00.00.00 /console
Replace “00.00.00.00” with your server’s IP Address.
