Remote Desktop Services sessions are not kept alive as expected in Windows Server 2008 R2


Consider the following scenario:
  • You install the Remote Desktop Session Host role service on a computer that is running Windows Server 2008 R2.
  • You enable and then apply the Configure keep-alive connection interval Group Policy setting in the following path in a Group Policy Object (GPO):

    Computer Configuration\Policies\Administrative Templates\Windows Components\Remote Desktop Services\Remote Desktop Session Host\Connections\Configure keep-alive connection interval
  • You create a Remote Desktop Services session to the Remote Desktop Session Host server from a client computer.
In this scenario, the Remote Desktop Services sessions are not kept alive as expected. This behavior may cause the Remote Desktop Services sessions to be disconnected.


This issue occurs because the Remote Desktop Services service does not apply the keep-alive setting successfully in some specific situations. This behavior can be triggered by a Group Policy refresh on the Remote Desktop Services session host.
