Use Ethernet
Get a router and add Ethernet cards to any computers that need them. Then connect all machines to the router.
Trying to "network" machines through dial-up modems is really doing it the hard way

Wow I tried to read that question and the typos made it difficult.

Anyhow, It appears you have a working network there and now you want to share your internet as well over it. this can be done two ways. The simplest is to purchase a router and plug your ADSL modem into the router (WAN port) then plug all the other computers on your network into the switch built into the router.

The second way is to enable ICS on your windows XP machine but you will need two network cards in that pc one to connect to the modem and the other to connect to the network switch or hub. To do this it is pretty self explainitory within the network setup wizard.
Keep in mind though using the ICS you will need to keep the host pc on anytime any of the computers want to connect to the internet and it will also be limited in speed to the weakest link in your network as well.

By far the best solution is to use a router to share the connection.

You need a router. wired or wireless depending on your setup.

Connect the incoming net to the router then each computer to the router.

While you are at it you might want to install the new gigabit network cards and cat6 cables. You can get the cards for $10.00 at the PC Club (on the net).
