I finally got my home network up and running! I'm running Windows 2000 and was having problems getting the computers on the LAN to see each other. They can all access the internet just fine, but when I'd go to "Network Neighborhood", "Find Computer", or "Computers Near Me" I'd get a big fat nothing.
Having exhausted all the logical possiblities, I decided to try something nonsensical. I went into my network connection properties and added the "NWLink IPX/SPX/NetBios Compatible Transport Protocol" protocol... and voila! Everything's peachy-keen! Just insert a few hours of frustration into the story and you'll get an idea for how exciting my life has been recently.
