After you use a slipstreamed installation to upgrade a computer from Windows NT 4.0, Terminal Server Edition, to Windows 2000 Server Service Pack 1 (SP1), the version information in the registry may not show that SP1 is installed. This behavior raises issues for programs that require installation of SP1.


To resolve this problem, obtain the latest service pack for Windows 2000. For additional information, click the following article number to view the article in the Microsoft Knowledge Base:
260910 How to Obtain the Latest Windows 2000 Service Pack


To work around this behavior, manually add the missing registry value:

WARNING: If you use Registry Editor incorrectly, you may cause serious problems that may require you to reinstall your operating system. Microsoft cannot guarantee that you can solve problems that result from using Registry Editor incorrectly. Use Registry Editor at your own risk.

  1. Start Registry Editor (Regedt32.exe).
  2. Locate and click the following key in the registry:
    HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion
  3. On the Edit menu, click Add Value, and then add the following registry value:
    Value name: CSDVersion
    Data type: REG_SZ
    Value data: Service Pack 1
  4. Quit Registry Editor.


Microsoft has confirmed that this is a problem in the Microsoft products that are listed at the beginning of this article.

This problem was first corrected in Windows 2000 Service Pack 2.
