Exeter NH, eh? For what it's worth, I am originally from Laconia... Back to your problem, now. Have you had a chance to check the mobo manual? Often times in 2k/XP, IRQs will be emulated, so you really should take a look in the manual to ensure that IRQs are not being shared on those slots. BTW, when you experience the problem is there any activity on the NIC? If you can't find your manual, let me know, I have a stack of manuals around that I can check for you.
