I believe a user left ArcGIS for Desktop open or left signed in on a computer in one of our Emergency Centers. It has been logged on for 5 days. I know no one is in that room as it was only being used for a training exercise. Do I just simply go into License Server Admin, click View License Usage, Checked Out, select the license type, select the user, and then click "Force Checkin"?
Update: This just re-opens the seat. If the application is open on the client side, it will re-ping the license server and re-take the seat. I just ended up remoting into the machine, closing the application, and logged out the user that left himself logged in.
