Repeating scheduled task is running out of schedule

Hi,

We have an issue where a scheduled task configured by GPO is running out of schedule on some devices. The behavior is so inconsistent that I could not come up with any logical explanation.

Requirements:
The task should run at every full hour from 20:00 (8 pm) to 7:00 (7 am) during the week and every hour on weekends.

Setup:

The triggers are defines as shown in the screenshot.
"Synchronize across time zones" is NOT enabled.
"Run task as soon as possible after a scheduled start is missed" is NOT enabled.

Problem:
On the device where I took the screenshot, everything is working as expected. The tasks starts at 20:00 and the last run is at 07:00.
However, there are devices where the tasks starts at 20:00 and keeps repeating until 10:00. Sometimes.

So while this happened yesterday, the same issue did not occur on the same device with the same network connection today:

My intuition was that this had something to do with time zone settings, but I compared them with another device where the issue did not occur so far and the settings were the same (same time zone, automatic daylight saving time switching enabled). However, even if wrong time settings should be causing the issue, then the start time should be delayed as well, but it is not.

Any ideas what I could be missing here?

Thank you!

    Hi Eleven,

    Thank you for your reply! I have attached screenshots of the task as applied on a computer as well as the XML configuration of the User GPO Task.

    Hi,

    Thanks for your information.

    It seems there is no setting problem as per the screenshots. In this case, you might need to capture some dumps or traces to further investigate the issue, which I suggest to contact Microsoft Customer Support and Services where more in-depth investigation can be done so that you would get a more satisfying explanation and solution to this issue.
     
    You may find phone number for your region accordingly from the link below:
