Symptoms

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.

Cause

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.

Important Windows 7 hotfixes and Windows Server 2008 R2 hotfixes are included in the same packages. However, hotfixes on the Hotfix Request page are listed under both operating systems. To request the hotfix package that applies to one or both operating systems, select the hotfix that is listed under "Windows 7/Windows Server 2008 R2" on the page. Always refer to the "Applies To" section in articles to determine the actual operating system that each hotfix applies to.

  • The files that apply to a specific product, milestone (RTM, SPn), and service branch (LDR, GDR) can be identified by examining the file version numbers as shown in the following table:

    Version

    Product

    Milestone

    Service branch

    6.1.760
    1.17xxx

    Windows Server 2008 R2

    SP1

    GDR

    6.1.760
    1.21xxx

    Windows Server 2008 R2

    SP1

  • The MANIFEST files (.manifest) that are installed for each environment are listed separately in the "Additional file information for Windows Server 2008 R2" section. MANIFEST files and the associated security catalog (.cat) files, are extremely important to maintain the state of the updated components. The security catalog files, for which the attributes are not listed, are signed with a Microsoft digital signature.
