Event id 333

Hola, estamos teniendo problemas en una serie de servers, 3 en este
caso, aparece este mensaje constantemente en el visor de eventos en
system.

Aparece cada 5 o 10 segundos. Se ha parcheado con el hotfix M898060.
Pero sigue igual el asunto.
Son servidores con Windows Server 2003 SE, SP1.
XEON CPU E5310 1.60GHZ
3,75 GB RAM.
