Terminal Service: Has Exceeded Maximum Number of Allowed Connections

If you encounter the following error
"The terminal server has exceeded the maximum number of allowed connections”
you generally call the System Administrator to terminate some invalid session and try again.

There is a WORK AROUND. Try this

Invoke the Run command and execute the following script

mstsc /v:000.000.000.000 /console

Replace 000.000.000.000 with your Server’s IP or Server Name.
