Cause: The type of certificate you are requesting is not available.

Solution: Contact your administrator.

Cause: In order for clients to receive certificates, they need to be able to contact the certification authority (CA) that will process the request.

Solution: If a CA is intended to be offline, the certificate request must be processed manually by copying it to removable media and physically carrying it to the CA for processing. Otherwise, wait until the CA is once again online and try again.

Cause: If the CA is online but enrollment still fails, autoenrollment permissions might have been configured incorrectly.

Solution: An administrator must modify the access control list on the certificate template to grant Read, Enroll, and Autoenroll permissions for the intended recipients of the certificate.

Cause: The CA Web Enrollment pages on the server that you are attempting to contact need to be updated to process certificate requests from this version of Windows.

Solution: Contact your administrator.
