When trying to connect using a remote desktop session you may get this Login Failure Message, because there are too many remote sessions
To resolve the exceeded connection issue execute "mstsc /admin" ( mstsc /console )command from the command prompt as shown below
If a terminal server has exceed the maximum number of sessions an "/admin" session can still be created and this will allow you to still connect to the server.
The /admin sessions don't count towards the session limit that may be configured on a terminal server to limit the number of remote sessions, so this will give you a back door into the server if you get the message "The terminal server has exceeded the maximum number of allows connections".
