2 different methods of MS Terminal Service Remote Admin
Here's an easy way to connect to the remote console of a TS server... useful if you get "The terminal server has exceeded the maximum number of allowed connections." error message.
mstsc /v:10.10.0.1 /console
Where 10.10.0.1 is the IP address of the server in question. You'll have to boot a logged in console session account, if any. But, this proves that in remote admin mode you really can have 3 remote sessions.
From the command line, you can use the following to query RDP sessions.
qwinsta /server:10.10.0.1
Then to clear the "slacker" idle session (session 1), use
rwinsta /server:10.10.0.1 1
which is IP address plus ID number.
