i have a gpo for scheduling a task to automatically restart domain computers at a specific time.  I have one executive who works late so I want to disable that gpo for him, and as such, moved him and his computer to new ou's in ad.  the scheduled task is now removed from his computer, yet the computer keeps restarting at the scheduled time as if the gpo is still in force.  I need help figuring out how to prevent his pc from restarting at 6pm. Below are some logs of interest from the event viewer:

Shortly after these events the OS logs kernel power manager and shutdown followed by the restart.


I need to get this behavior to stop, so any help would be GREATLY appreciated.
Thanks in advance.

Would it help if you remove the "%SystemRoot%\PSSDNSVC.EXE" file from his PC?

Author

Commented:
was thinking about that, but was unsure if that would negatively impact other functions of the OS.  Does that exe need to be there for anything else?

The psshutdown.exe utility which you are using for the shutdown/reboot is part of a collection of tools from SysInternals.  

https://docs.microsoft.com/en-us/sysinternals/downloads/psshutdown

So it is not in use by the OS itself.  It is actually a separate install.

Commented:
Yes, I see that the file should be in that directory, but I am doing a search and cannot find it anywhere

Interestingly, it seems that the service is installed daily.  I see this in the event viewer daily, when I search for psshutdown or pssdnsvc.exe I cant find anything:

also found this in the event viewer's task scheduler filter.  this shouldn't be happening.  the gpo that generated that task was removed from this pc.  furthermore, this task is not even in the task scheduler on the front end.  It seems that the policy removed the task from the scheduler, but somehow it is still running.

Is there another gpo which is installing the reboot utility and then removing it once the task has ran?

Author

Commented:
I don't see one anywhere, but it sure seems like it.  I will run an rsop and see what is coming in and then update the post

Author

Commented:
Ok, I scoured the RSOP and there is nothing coming in that would issue a restart command.  I am out of ideas here.

Can you try running "schtasks" on a command prompt.  This will list all scheduled tasks on the machine.  See if any task which is doing the reboot.
