A user may log on successfully to a computer when either of the following conditions is true even though their smart card certificate has been revoked or their user account has been disabled in Microsoft Windows XP:
- If the smart card certificate of the user has been revoked and the user has tried unsuccessfully to log on online at least one time, the user may still be able to log on offline and have access to network resources by using the NET USE command.
- If the account of the user has been disabled in the Active Directory directory service and the user has tried unsuccessfully to log on online at least one time, the user may successfully log on offline.
This problem may occur because the cached credentials for the user are still enabled.
