SYMPTOMS
Consider the following scenario. You install a security package on a Windows Vista-based computer. Then, you restart the computer. In this scenario, the computer restarts repeatedly. Specifically, after you restart the computer, the Windows Vista startup screen appears. However, the computer then restarts instead of finishing the startup process.

This problem occurs if the security package is signed by using the method that is described on the following Microsoft Developer Network Web site:

http://msdn2.microsoft.com/en-us/library/ms925908.aspx

Note The security package that causes this problem may be offered by a third-party cryptographic service provider. A security package is a software implementation of a security protocol.



RESOLUTION
Generally, you cannot recover the Windows Vista-based system after this problem occurs. The following hotfix only prevents this problem. You must install this hotfix before you install the security package.

If this problem has already occurred, you must run a repair installation of Windows Vista.
