Symptoms

When logging into a Denallix VM via Remote Desktop Connection, then the user automatically gets kicked off after 1 hour of being idle or disconnected.

 

Diagnoses

We checked Group Policy and made some changes there, but it turns out the values have been set in the registry and that overrides Group Policy (could be a Windows bug).

 

Resolution

There are two settings in the registry:
MaxIdleTime and MaxDisconnectionTime

Both can be deleted (or probably set to 0) in order to disable this behaviour.

There is also a PowerShell script called "Enable RDP KeepAlive.ps1" attached to this ticket and should be in C:ResourcesScripts that should also help regarding this, but please double check the registry as well.

The entries should be in HKLM:SOFTWAREPoliciesMicrosoftWindows NTTerminal Services
