Looks like the problem is related to a CA that it doesn't exist anymore.


 If there is no CA in your domain, you can ignore this event.
*  Install a CA in the domain.
*  If there is a CA in the domain, request a new domain controller certificate from the CA. For more information, see the following Microsoft Knowledgebase article:
