The first thing I do is give my tank the boots of speed and anything that enhances missile weapon protection and have him go open the door and come back. Then I heal him up, cast haste on the party and make a run for the door (it's the only thing you can do, really). Once inside, I immediately hit pause and target the archers "man to man" I forget how many archers are in there, but I usually play with 5 or 6 characters, so this works. Of course, send the best hand to hand fighters up against the guys you can reach and use ranged weapons/spells for the rest. Then it's just a matter of paying attention to what's going on and, when one of the enemy dies, targeting someone else.

Hope this helps.
