David,

>Thanks for the tips, David. That's great experience that I'll take advantage of. I haven't heard back from them yet, so I'm hoping that moving the temp files to the local drive was good enough. If not, I have the politically sensitive task of questioning their network guys! That's great to know about switches - I had no idea. Thanks.

Someone correct me if I'm wrong, but I believe that in most cases a switch can enable full duplex communication (20/200) with your netcard in addition to isolating the traffic from being heard by other cards.
