Problems With Smart Card Logon on Windows Vista

If you are having trouble with smart card logon/user certificate in Windows Vista/IE 7 client, check out Microsoft’s Knowledge Base article 922706. It states that:

“The Windows Server 2003 Certificate Services Web enrollment functionality relies on an ActiveX control that is named Xenroll. This ActiveX control is available in Microsoft Windows 2000 and in later versions of Windows. However, Xenroll has been deprecated in Windows Vista. The sample certificate enrollment Web pages that are included with the original release version of Microsoft Windows Server 2003, with Windows Server 2003 Service Pack 1 (SP1), and with Windows Server 2003 Service Pack 2 (SP2) are not designed to handle the change in how Windows Vista performs Web-based certificate enrollment operations.”

The Knowledge Base article discusses how to use Certificate Services Web enrollment pages together with Windows Vista.
