4886: Certificate Services received a certificate request

On this page

When the Certification Authority receives a certificate reqeuest it logs this event. 

Then it evaluates the request, loading the relavent certificate template if appropriate (event 4898).  Then the CA will place the request into the Pending Requests folder (4889), immediately issue (4887) or deny it (4888). 

This event event is only logged if "Issue and manage certificate requests" is enabled on the Audit tab of the CA's properties in Certificate Services MMC snap-in and of course if the Certificate Services audit subcategory is enabled with auditpol.

Request ID: The certificate request is identified by the Request ID.  To get the details on the request including who requested it you will need to look in the log for other events with the same Request ID.

Requester: the account that requested the certificate
Attributes:  unknown.  if you have information to share on this event please start a discussion.

Attributes: attributes taken from the certificate template and request

UserAgent: the browser ID or other program that submitted the request

ccm: apparently the computer name of the client
