Unusual Problem

[Guest]

I have a office network with has 4 PCs.
1 of them has two lAN cards one for network and another for cable internet.
I am using Intenet Connection Sharing to access internet on other 3 PCs.
They are connected via HUB and Running on Windows XP Profesional with SP2.

Now i want to connect a 5th PC but i dont have a long cable which can reach
to HUB. So i want to connect it to the nearest PC(Say A).
I want that it should only be able to access A and also access internet.
A PC also has 2 Ethernet cards. one connected to existing network and
another is free.
How can i achive this.
Thanks In advance.

Buy a small hub to join the extra cable into the network. They're very cheap
these days.

A crossover cable connecting both machines and then internet sharring on the
machine with two nics.
The bigger question is Why? A longer network cable is pretty cheap.
Especially if you make it yourself.
