Microsoft DNS server errors 5501 and 5504

Kind of interesting, I have a client that is having issues with a specific DNS server. I did not setup their AD topology, so bear with me here.

The issue is described to me as happening after a power outage (not sure if this is 100% accurate), but when it happens, users at a specific site are unable to resolve DNS hostnames.  Durning this period the DNS server is online, wit hit's services up, but there are no entiries in the lookup zones.  Rebooting and allowing to sync the DNS server resolves the issue.

The users are pointed to this server as their primary DNS, and have another internal server as secondary (and google dns as tertiary) .  Even though the 2nd & 3rd dns servers are fully functional, the clients who point to this as primary, can't resolve.

The main thing I see, is during the outage, I see a ton of Event ID's 5501  and a few 5504 errors with public IPs.
