active directory – GPO doesn’t run script/program

Good morning everybody,
i’m trying to automatically shutdown our company’s computers every day at 19:00 so I set a group policy that runs C:WindowsSystem32shutdown.exe etc etc.

The GPO is correctly deployed and I can see the scheduled task but it doesn’t run shutdown.exe or any program (even manually)

I think the problem is on the account running the scheduled task (System) but I tried the logged user and the domain administrator but the scheduled task never showed up.

This thing is driving me crazy.

Can you help me?

Thanks a lot in advanceenter image description here
