How to obtain help and support for this security update

Back to the top

• After you install this security update on a Windows XP-based computer, you may receive an error message that resembles the following:
  
  
  :5.375: FileVersion of C:\WINDOWS\system32\mstscax.dll is Less Than 6.0.6001.0 for QFE branch
  This problem only affects Windows XP based computers that were updated by using updates to address specific issues that are not delivered by Windows Update. For example, computers that have "Limited Distribution Release" (LDR) branch updates installed.
  
  To work around this problem, use either of the following methods:
  • Uninstall security update 956744 (http://support.microsoft.com/kb/956744) , and then install security update 2481109.
  • Alternatively, if you already have security update 956744 installed, you can install hotfix 967885 (http://support.microsoft.com/kb/967885) . Then you can successful install security update 2481109.
• If you have the Remote Desktop Connection (RDC) 6.0 Multilingual User Interface Pack (MUI) installed, you must install the RDC 6.1 MUI for RDC to work with MUI.

• Connections from the Remote Desktop Microsoft Management Console (MMC) snap-in on computers that have RDC 6.1 installed do not connect to the console session on the server. (The console session is also known as the "admin" session).
• Consider the following scenario. You upgrade from Remote Desktop Connection 6.0 to Remote Desktop Connection 6.1. Then, you run a system restore procedure. In this scenario, the system restore procedure fails to restore the Microsoft Terminal Services Client (MSTSC) Remote Desktop Connection 6.0.
• After you install this security update (the security update for MUI for Remote Desktop Connection 6.1), the Remote Desktop Connection shortcut text on the Start menu always appears in English.

• Question Before I installed security update 2481109, I had RDC 6.0 running. After I installed the security update, I am running RDC 6.1. Why?
  Answer Microsoft does not service RDC 6.0. Customers are migrated to RDC 6.1 with this update.
