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.

Attributes:  unknown.  if you have information to share on this event please start a discussion.
