For Microsoft Windows Server 2003 version SP2, update to a version that includes the fix for this issue. For Microsoft Windows Vista version SP2, update to a version that includes the fix for this issue. For Microsoft Windows Server 2008 versions SP2, R2, and R2 SP1, update to a version that includes the fix for this issue.

As a temporary workaround, consider disabling the use of revoked X.509 certificates for domain accounts until a patch is available.
