Remote Logoff Windows

When the above message appears on a machine, this indicates that there are too many users logged on at once.
A reason for this could be a user on wireless connected remotely to the machine, losing the wireless connection and connecting again with a different I.P address once the wireless connection is reestablished. This can also occur when moving from a wireless connection to a wired connection if a new I.P has been issued.

From cmd on a machine in the same domain as the machine with too many users logged on
run:

Quser.exe /server:<serverName>
This gives us the list of active sessions on the machine

logoff <sessionId> /server:<serverName>
This will logoff the session for the sessionid specified

Example:
Quser.exe /server:DestinationAddress

logoff rdp-tcp#11  /server:DestinationAddress

Result:

Problems:

If "Error 0x00000005 enumerating sessionnames" is seen, then the machine that you are trying to access is on a different domain.
You need to be on the same domain.
