We're seeing issues with workstation shutdown consistency.

I was just using a Shutdown bundle, but a lot of times, the machines would be asleep and think they needed to shutdown after waking and logging in. They usually get a prompt, but sometimes don't or don't see it.

I tried using this method:

We're on 11.4.3, now. Planned on moving to 2017, but not in a hurry. If that would help with issue, then I might be more inclined to get the upgrade done sooner than later. We have about 1000 workstations, 800 of which I want to shutdown regularly.

Is there anything else I can look at or do to make this work properly?
