SYMPTOMS
If you uninstall Windows 2000 Service Pack 1 (SP1) from a computer that has Windows 2000 High Encryption Pack (128-bit) installed, the encryption may be reduced to 56-bit.



CAUSE
This behavior occurs because Windows 2000 SP1 removes the High Encryption Pack files. Therefore, you cannot restore it after the Windows 2000 SP1 uninstallation.



RESOLUTION
To work around this problem, reinstall Windows 2000 High Encryption Pack (128-bit) again from the following Microsoft Web site after uninstalling Windows 2000 SP1:

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



MORE INFORMATION
The Microsoft Windows Update Web site may incorrectly show that Windows 2000 High Encryption Pack is installed even though it actually is removed after SP1 uninstallation.
