UPNP was already disabled on router, but it wasn't in Vista. That's done now. I didn't realize that "Network Discovery" was the new name for UPNP. Good to know. We'll see if this fixes anything. I'm not sure if it only happens when my vista computers were on though...we'll see I guess.
Thanks for the replies guys!
