Do you have two network cards? You have to have two cards, one that connects to the net and the other card that the computers use to connect to your “server”. Usually when it says “other computers cannot connect to the internet through this computer” it is because there is only ONE network interface which just does not allow network sharing!

Basically you are turning your computer into a router for the other machines and that needs more than one network connector in order to work.
