Unable to connect my 2 computers

[Denis54]

I own the following equipment:

P3 1 Ghz, 512 MB RAM, Realtek 8139 NIC, XP Pro
Toshiba 4090 XDVD notebook, Celeron 400, 192 MB RAM, 3Com FE574B NIC, WIN 98 (not SE)
SMC 7004 VBR router
Cable modem
C drives in both computers are shared

Both computers acces the internet through the router without any problem. I would like both computers to communicate with one another. So far I have been unable to do this.

How do I need to setup my computers to do this? Is there any web site I can visit to learn how to do this. I have setup networks like this on my previous computers. I am not a complete newbie but I am far from an expert.

How exactly are the two PC's connected to each other?

Each computer is connected to the SMC router. The SMC router is connected to my cable modem

Hmmmm....does the router have some kind of hub or switch built in?

Can the two PC's ping each other?
