Wish I could give it a better title, but have no idea what the problem is. Here are the symptoms: my network has 12 PC running W2K and some XP we share the internet via a switch/router. Most if the time it works like a charm, but all once of a while the router goes crazy resetting itself. On the old hub network I found a worm once which caused us trouble, but with the switch I have no idea how to analyze the problem. Any idea on how to go about fixing this?
