SYMPTOMS

Consider the following scenario:
  • You install the Terminal Services role on a computer that is running Windows Server 2008.
  • You configure some Terminal Services RemoteApp (TS RemoteApp) applications on the terminal server.
  • You start an application by using Terminal Service Web Access (TS Web Access).
In this scenario, the started RemoteApp application is intermittently not visible on the client, even though the application has started successfully on the server.

CAUSE

This issue occurs because of a race condition in the RDP Shell (Rdpshell.exe). When the race condition occurs, the RDP shell cannot obtain the window region of the started application. This behavior causes the started application to lose visibility intermittently.

Windows Server 2008 file information notes
Important Windows Vista hotfixes and Windows Server 2008 hotfixes are included in the same packages. However, only "Windows Vista" is listed on the Hotfix Request 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, SR_Level (RTM, SPn), and service branch (LDR, GDR) can be identified by examining the file version numbers as shown in the following table.
