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.
