Can I share Internet access across LANS?

I have one PC that is connected to a LAN and gets internet acces from it, but now i bought another pc and want to connect the two using a crossover cable, so both can share internet access from the first PC. Is this possible, or I am missing something? Does the first PC needs to have direct access to the internet? (Not through the other LAN?).
P.S.: Connecting my second PC to the same network of the first PC is not possible.

Please explain… Why isn't it possible? What kind of network is it? In the dark… Larry

My two PCs are networked using NICs and a crossover cable, and they work fine. The problem is when I try to configure the Home Networks Wizard on both PCs, none of then has internet access. But as soon as I tell the wizard that I don't use the internet and reboot, I have internet again.
I can't connect my second PC to the network that gives me access because their hub has all its connections full, and if I want access I would have to buy one to replace it.
I would really appreciate if you could help me with this.
THX!!

You could probably use a Network Address Translator (NAT), such as ICS (http://duxcw.com/digest/Howto/network/win98se_cab/intro.htm) and Sygate (http://duxcw.com/digest/Reviews/Network/sygate/sygate.htm) to do it, but it would be much better just to purchase cheap hub or switch. Simply connect the uplink port on the hub or switch to the line going to the computer already on the network, and straight-thru cables from the hub to the PC’s. I assuming that the existing network is not already layered with hubs. Larry
