You may want to see which users are logged on to your Windows 2012R2 Server at any given time and may want to logoff a user. Users can be active on a server or in a disconnected session status which means they disconnected from the server but didn’t log off. Since disconnected sessions continue to utilize server resources, we recommend you enable a group policy to log off disconnected sessions automatically after a specific time period such as 1,2,4, or 8 hours – see our blog post here on how to enable this group policy http://www.RiptideHosting.com/blog/how-to-set-time-limit-for-disconnected-sessions-windows-server-2012r2/
We haven’t seen this happen very frequently, but if a user logs on to the server and the screen remains black, it is likely because the user has an existing disconnected session that has not be fully logged off. To resolve this, log into the server as an Administrator and log off the User’s disconnected session. When the User logs in again, they should see their full desktop session without any issues.
Steps to view and log off users:
- Login as Administrator or account with administrator rights
- Open Task Manager by right clicking the bottom tool bar
- Click on “More” or “Detail” to view all tabs of Task Manager
- Go to the “Users” tab which will show the users that are logged on the server
- Right click on a username and select “Log Off”
We recommend that users be educated to log off from the server when their tasks are completed (start, click on username, select log-off or sign-off) instead of just disconnecting the session by clicking the X in the upper right corner which doesn’t log the user off and only disconnects the session.
