Chad,

How many computers do you have - two or three? How are they connected?

Specifically, what is connected to the cable modem? Did you connect the XP
computer after the other one (two?) was working?

Am I reading you exactly correct - is it a HUB connected to the modem? If
that's it, then you are wasting your time.

Only ONE computer can connect to the cable modem and get internet connectivity.

You need to replace the HUB with a NAT router. The router will share the
internet connection.

OK, there's the problem. A switch doesn't help share the internet connection -
so the modem sees the first computer connected as its client.

You'll need to get a router to replace the switch. Costs about a couple months
DSL service. Both computers will be safer, with it NATing them to the internet.

so why did it work with 2 NT4 machines. not with XP. I can turn off the one NT4 machine and the XP machine still won't get past the cable modem? It seems like XP as something stuck in cache?!?? I certainly appreciate your help!!!!!
Thanks.

Chad,

You're asking a very interesting question.

This is what I know about cable modem service:
1) The cable modem starts up.
2) It gets the MAC (physical) address of one computer connected to it.
3) It connects that one computer to its network.
4) That one computer is issued an ip (network) address by the DHCP server run
by the cable company.
5) With a DHCP issued ip address, that one computer can now send and receive
internet traffic.

If your service is for two ip addresses, you might get service (ip address) for
two computers. But the vast majority of cable broadband is for one ip address.

If you need internet service for more than one computer, you connect a NAT
router directly to the cable modem, and any computers to the router. The modem
sees the router, and the router sees the computers.

See internet sharing tutorials on these websites:
<http://www.cablesense.com/>

Try turning the NT computer off, then turn the modem off for 10 - 15 minutes.
With the XP computer on and the NT computer off, turn the modem on, and see what
happens.

Please provide ipconfig information for each computer.
Start - Run - "cmd". Type "ipconfig /all >c:\ipconfig.txt" into the command
window - Open c:\ipconfig.txt in Notepad, copy and paste into your next post.
Identify operating system (by name and version) with each ipconfig listing.

Cheers,
Chuck
