Here’s an easy way to view RDP sessions for other servers from the command line and log them off if you need to. The only requirement for this is that you are a domain admin.

From an elevated command prompt, run the below the command, replacing <server> with the hostname or FQDN of the server you want to view the sessions of.

qwinsta /server:<servername>

This will show you a list of all sessions logged into that server.

If you want to logoff one of these sessions, run the below the command replacing <session ID> with the session ID which you want to logoff, which is shown in the above command.

logoff /server:<servername> <session ID> /v

This will then log off the session.

Hope this helps!
