Problem:

How to determine whether a user is logged onto a workstation remotely.  For example, the help desk wants to remote desktop to workstation for maintenance purposes.  This task requires that no other user is logged onto the workstation.  Help desk does not want to disrupt any staff that may be working on the computer.

Solution:

Use Query Windows Station (qwinsta) to list active sessions:

qwinsta /server:hostname_or_IP

Hint:

Combine this with the reset session command as needed:

reset session {SessionName | SessionID} [/server:] [/v] That's It!
