Server 2012 (PDC) is throwing up errors with Event ID 413, 418 & 454 every couple of minutes (Source ESENT).

My PDC has been throwing up errors with Event ID 486, 454 & 413. These three errors occur in sequence every couple of minutes. Most of what I have found indicate that this is a problem relating to an Exchange database. However, this server is my PDC and is not running Exchange.

Here is more information relating to Event ID 486:
