Ah, I had a similar problem (in addition to the quest minion one, lucky me) with Unknown Entities. It was in fact my network drives (nvidia nforce integrated), I just had to toggle a setting in there. I can't remember the name, but he official WoW knowledge base describes the problem.
When I had that, it didn't have anything to do with quests. The Quest disconnecting I got was from QM alone.
