I will be home from college for a little more than a month, and because its the holiday season, Im a little tight for cash right now, so a router isnt a high priority. My computer has 1 integrated NIC, and I had one cheap PCI NIC laying around that I stuck in there. I have an ethernet cable running from my DSL modem to the PCI NIC, and then a crossover cable running from the integrated NIC to the NIC on the other computer in the network.

My computer is XP Pro, the other computer is XP Home. Both have "Obtain IP addresses automatically" checked in the TCP/IP config properties.

I tried to enable internet connection sharing and using Windows' Networking Wizard thing-a-ma-jig and the other computer would never get a connection. I was able to bridge the connections for a day, went to bed, and woke up to about a million balloons popping up from my task bar alerting me to "IP adress sharing conflict" or something of that sort, with no "click here to fix" link. At this point, the internet on both computers dies.

The only way to get the internet to work from that point is to remove the bridge.

Task - get both computers connected to the internet.

i didn't read the whole massage, but i understand that you want to use a computer as a router, it's possible!
first, you've got to understand that if you want that advanced you will have to lose one computer.
second, it's demands you to install a linux operating system on the unused computer.

What part of internet conection sharing didnt work for you?

Did you reboot the other computers connection after you setup ICS or use the repair feature. Basically what that does is force the computer to renew its IP address.

Eh, are the two computers actually networked? Like they have internal IP addresses? Eg 192.168.0.1.

I'm not a windows guy, but I'd have to guess that the same IP was issued to the other PC since the request went to the router from the first PC (and subsequent MAC address,) and the router simply issued the same IP due to the MAC. I'd be willing to bet that if you configured a static IP you'd be OK.
