I'd look at a hardware conflict with the drivers. Sound card and video are the first that come to mind that might be stepping on the IRQ that the NIC needs.

It is recognized in the Device configuration screen, but I can't get any logon - it won't display the other computers in the network (I am connecting into a college ethernet system from my apartment). Someone from the college came and tested the wires and the jack, and both are good. I spent 11/2 hours on the line with a guy @ 3Com, but we couldn't make any headway. He suggested I go through a complete uninstall/reinstall of all of the Dial-Up networking files via Microsoft's instructions from their knowledgebase. So I uninstalled the driver, physically removed the card, and followed the instructions. At the end of it all, it's exactly the same -- no logon. The diagnostic tool that came with the card says that the network connection works, but when I run the diagnostic tool on the NIC itself, it crashes thae computer and restarts it. Any ideas?
