Terminating a Remote Login Session on a Windows Client

There's two parts, the list sessions (query session) and the terminate session (reset session).

First, the list session. the command below will list all the current sessions that a PC has, both local and remote.

qwinsta /server:[servername]

Once you have the session you want to terminated, find the ID number beside it and use this command to terminate that session

rwinsta /server:[servername] [ID]
