Consider the following scenario. You have Windows Server 2003 with installed Certification Authority and Web Enrollment components. When you try to access web enrollment pages from a Windows Vista-based (or newer) computer you receive a message box:
The certificate enrollment page you are attempting to access cannot be used with this version of Windows.

To learn more about this issue and the steps needed to update Web enrollment pages to support all versions of Windows, see: http://support.microsoft.com/kb/922706
KB922706 page contains the following information:
Security update MS11-051 replaces the fix in 922706 and we advise customers to install the security update 2518295 instead of this hotfix 922706.
After installing MS11-051 patch (KB2518295) an error remains and you still cannot use web enrollment.
The patch MS11-051 (published 13 June 2011) does not replace KB922706 for Windows Server 2003.
Windows Server 2008 and Windows Server 2008 R2 are not affected, because they already have KB922706.
Microsoft is working on MS11-051 patch update. See Workaround section how to work around the issue.
