If you have the problem of not being able to log on to a server because it has exceed the maximum number of connections (usually 2) here is an easy fix.
Open a command prompt and type:
query user /server:{YOUR SERVER NAME}
You will get something back like this:
| USERNAME | SESSIONNAME | ID | STATE | IDLE TIME | LOGON TIME |
| user1 | 1 | Disc | none | 2011-03-10 20:25 | |
| user2 | rdp-tcp#121 | 2 | Active | 6 | 2011-03-20 11:29 |
You can then either ask the users to log off or you can forcibly log them off by typing:
logoff {ID FROM ABOVE} /server:{YOUR SERVER NAME}
If the query user syntax doesn’t work (e.g. Win XP) you can type:
qwinsta /server:{YOUR SERVER NAME}
