Starting with SP4, events are logged during the certification authority (CA) certificate chain-verification process when an invalid certificate is detected. This message DOES NOT indicate a problem with the current certificate.

Your only workaround is to ignore the Certificate Services did not start portion of the event description for events that are logged during the CA certificate chain-verification process.
