1. With Remote Desktop, you can connect to your work computer from home and access all of your programs, files, and network resources as though you were actually sitting in front of your computer at work.
2. But, if you encountered this error while accessing the remote desktop connection, you can actually bypass the remote desktop connection. This problem occurred because Windows only allows 2 remote terminal services connections when you are in administrative mode.
The terminal server has exceeded the maximum number of allowed connections.
3. Go to your command prompt (Start -> Run). Apply below command and you are done. Try the remote desktop connection again.
C:\> mstsc /admin
