One of the primary functions of a certification authority (CA) is to evaluate certificate requests from clients and, if predefined criteria are met, issue certificates to those clients. In order for certificate enrollment to succeed, a number of elements must be in place before the request is submitted, including a CA with a valid CA certificate; properly configured certificate templates, client accounts, and certificate requests; and a way for the client to submit the request to the CA, have the request validated, and install the issued certificate.

Enable revocation checking for all issued certificates

To fix this problem, enable Online Responder revocation checking for all time-valid certificates issued by the certification authority (CA).

To perform this procedure, you must have Manage CA permission, or you must have been delegated the appropriate authority.

To enable Online Responder revocation checking for all time-valid certificates issued by the CA:

• Open a command prompt window on the computer hosting the CA.

• Type certutil -setreg ca\UseDefinedCACertInRequest 1 and press ENTER.

• Click Start, point to Administrative Tools, and click Certification Authority.

• Select the name of the CA, and then click Restart.
