Task Manager not Repsonding in Windows 2012


We have a Windows 2012 server and when i right click the task bar and click the task manager the window is blank  and the timing glass is thinking. If i click on the task manager windows, it says ( Task Manager not Responding).

I left for 30 minutes and nothing happened and also restarted the server it is the same . When I try to close the blank task manager windows I get the message saying check for the solution  and restart the program. Please see the snapshot.

Any help to resolve this would be great.

Try running DISM.

Open cmd.exe with Run as Administrator and run dism.exe /online /cleanup-image /restorehealth  
Allow this to complete and restart again, then test.

If DISM does not work, you may need to try a Repair Install with the Server 2012 Media.

Do I need to take a downtime on the server or is it ok to run the DISM on the live environment, .

You can run DISM on the live environment but you should restart upon completion of DISM.
