I am replacing some Windows Server 2008 R2 boxes with new Windows Server 2019 boxes. Both sets are mostly administered over RDP.
The new 2019 set kicks RDP sessions back to the login screen after a certain amount of time idle; I am not sure how long, but something between 10-30 minutes. When I'm working on many servers at once and switching between them, this gets very frustrating very quickly. The old 2008 R2 set does not do this.
I could not find any configuration difference between the two sets. I've tried the following via group policy settings on the new set:
Microsoft Network Server: Amount of idle time required before suspending session(600 minutes)
Interactive logon: Machine inactivity limit(86400 seconds)
Turn off the display (plugged in): (10 hours)
They successfully apply, but none of them helped. I checked screensaver settings too (grasping at straws), and screensavers appear to be disabled by default (which makes sense). I couldn't find anything else that might require login after idling.
Clearly I'm missing some setting. But where?
