Multihomed Server

I have a PC dual-bootable. When in Win98, I am hooked up to DSL service. Alos have a 2nd NIC installed that shares IRQ with USB controller. That NIC won’t work even though all checks (ping) appear to be good.

When booted to NT4, IRQ 9 is used (solely by 2nd NIC). IT will not work there either! The NIC is good because I pulled it out & tested it as the client PC NIC (another machine). Any ideas!
