Before I conscript Microsoft's wonderful tech support on this issue, I figured I'd ask here for assistance as there are at least 100 people here smarter than me
Deployed new Server 2016 instance with my typical GPOs for security and computer settings.
I typically have monitor blank configured for 15 minutes and lock after blank.
The customer has decided that 15 minutes is far too short and, despite my concerns, wants 120 minutes.
No worries, I'll just change the GPO for those that need this.
I change the Computer/Policies/Administrative Tools/System/Power Management/Sleep Settings to reflect this.
The computers -- All Windows 10 Pro -- show 2 hours in their settings but cannot be changed by the user as this is pushed via GPO. All good right?
We receive a phone call that the computers are still locking after 15 minutes.
GPO looks good, Windows looks good.. As a test, let's remove the forced power plan from GPO and let a user adjust it.
Reboot the computers and they default to 15 minutes for display sleep and allow changing to 2 hours.
15 minutes later, the displays are all sleeping again. Arrgg!
Ok, forgot that Windows 8+ have a "Interactive logon: Machine inactivity limit" that needs to be set and it's currently at 900 seconds.
Let's change that to 7200 seconds and see.
15 minutes later and the monitors are sleeping again.
I have checked the powercfg (and restored default settings), registry, etc and all show that machine inactivity is 7200 seconds, power plan shows 2 hours but STILL the monitors blank after 15 minutes.
Has anyone run into this before and can offer some assistance before I spent the next week back and forth with MS?
Thanks!
