event ID 2000 flood

Every couple of weeks our server gets flooded with these Events, and we have to shut it down manually to get anything to respond.

They are literally coming a few per second.

 

Anyone have any idea on this? This keeps happening more and more often, and competely paralizes us until we hit the power button on the server. I got a tip that suggested uninstalling windows 2003 SP 1, but not sure how valid that is.

We are really hurting.

Thanks.
