Consider the following scenario:

• You have a computer that is running Windows Vista or Windows Server 2008.
• You try to log on to a Windows Server 2008-based terminal server by using smart card authentication.

In this scenario, the logon operation fails. Additionally, you receive a “0xC000040C” error message.

Note: The “0xC000040C” error code means that the revocation status of the domain controller certificate that is used for smart card authentication cannot be determined.

This issue occurs when the cached certificate revocation list (CRL) of the domain controller certificate on the client has expired.

You use a Remote Desktop Protocol (RDP) session to log on to a terminal server that is running Windows Server 2008 or Windows Vista with Service Pack 1 (SP1). However, when you run an application, such as a Microsoft Visual FoxPro application, the terminal server may randomly crash. Additionally, you receive an error message that resembles the following:

Stop 0×0000008E
KERNEL_MODE_EXCEPTION_NOT_HANDLED

When you use the Remote Desktop Client to connect to a Microsoft Windows 2000 Terminal Server from Window Vista or from Windows Server 2008, the automatic authentication fails, and you are prompted two times for the credentials.

This does not occur when you connect to a Windows Server 2003 Terminal Server.
