Occasionally, folks on my support team will accidentally disconnect from an ICA session at a client location, and I’ll need to log into that same server via RDP with our shared support account and can’t due to the disconnected ICA session.  Rather than taking the time to log into StoreFront, and reconnect to that disconnected session, the quickest thing to do is log it off.  Here is a pretty simple two liner you can run against a remote server to enumerate the user sessions and log a session off.

In an administrative command prompt run:

query session username /server:servername           (where username is the user you want to log off and servername is the server they are logged into, or skip username to show everyone logged in)

Query will return the sessionname, ID, and state of the user’s connection.  To log the user off, run:

logoff ID /server:servername           (where ID is the ID of the session from the previous command of the user you want to log off and servername is the server they are logged into)
