The Remote Desktop Web Access website does not show any published RemoteApp programs if a RemoteApp source is offline in Windows Server 2008 R2

Applies to: Windows Server 2008 R2 Service Pack 1Windows Server 2008 R2 DatacenterWindows Server 2008 R2 Enterprise


Consider the following scenario:
  • You configure a Remote Desktop Web Access (RD Web Access) server on a computer that is running Windows Server 2008 R2.
  • You install the Remote Desktop Session Host role service on some servers that are running Windows Server 2008 R2, and then you publish some RemoteApp applications on these servers.
  • You configure these Remote Desktop Session Host servers as the RemoteApp source of the RD Web Access server.
  • You shut down one of the Remote Desktop Session Host servers.
In this scenario, you notice that the list of the RemoteApp applications in the RD Web Access website is returned as blank.


This issue occurs because of a design flaw in the RD Web component. The RD Web component stops enumerating applications as soon as the component encounters a session host that is unavailable.
