Event ID 108 — AD CS Certificate Request (Enrollment) Processing

Applies To: Windows Server 2008

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.

Event Details

Resolve

Manually delete the certificate

A connectivity or permissions problem can prevent you from deleting a certificate. To resolve this problem:

• Confirm that you have network access to the location where the certificate is stored.
• Try to delete the certificate mentioned in the event log message by using one of the following procedures.
• If you confirm that you have network connectivity and still cannot delete the certificate, then confirm permissions on the Domain Users and Domain Computers containers in Active Directory Domain Services (AD DS) before attempting to delete the certificate again.

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

3. Click Start, type mmc, and then press ENTER.
