Thanks for the info people.

Well, I thought I could separate "file and printer sharing" from the internet but according to TropicalBound's and shiva's posts that isn't so. Only one NIC in each machine as we're on DSL modem and router. Each machine and the router has a separate IP assigned by the ISP so no DHCP action here.

So I'm left thinking I should just stay with what I've got, TCP/IP for the whole works and not install NetBEUI at all.

Then to make a baseball analogy, I'm sitting here at the plate with an 0-2 count and thinking I'm starting to understand the game and then PakRat comes in and throws me a changeup. Ooops, slipped the third one by me...lol. 0-3!

So what's necessary to separate file sharing from the internet?

And PakRat, if I'm not using NetBEUI, how does what you're telling me apply?

I've drilled down to the level where I'm clueless here. Always nice to find out that sort of thing before it's critical. Sure don't want to find it in an emergency.
