internet sharing with crossover?

I was wondering if someone could PLEASE HELP ME. Is there any way to share the internet with two computers through crossover cables and not using a hub? I'd appreciate any and all help. Thank you very much.

well...there's a catch here i forgot to mention. the computer im trying to make the "server" for my ICS to the other computer is already on an ICS network. it's a long story as to how/why I'm doing this. But basically my computer is on an ICS network i made through a hub...then i fixed my old computer and i wanted to hook this one back up to the internet so i'm trying to hook it up through my new computer through ICS also...so it's really complicated...but can i make an ICS network on a computer that is already part of an ICS network?

see, i planned to just plug it straight into another one with the net connection...which i did using a crossover cable. The computer i plugged it in to gets the internet through a hub. I mean, these 2 computers see each other no problem. I just can't seem to get the one able to use the internet. I don't know if it's even possible to share the internet via crossover cable. If anyone has info on how to share the net through crossovers, let me know. I tried ICS but can't get it unless I'm missing a network setting somewhere in the properties for the NICs...
