Good online D&D type games?

Does anyone know of an online RPG that you could play with just a group of friends, that had support for one person being like some sort of dungeon master?

You'll probably want to take a look at Neverwinter Nights, I think it fits the bill perfectly. It's based on D&D and there can be a dungeon master to set up the adventure. It has coop as well, but I'm not sure how many players. Worth a look though in any case

Cool I didn't know Neverwinter Nights had DM support.
