I know a lot about computers, but one THING that I am not too familiar with is networks.

I re-installed Windows XP Pro on my dads machine and I have the modem hooked up to his computer but No internet. I'm sure I'm missing important steps, but like I said, networking is not my thing. Please help me.

Machine Specs:
Gateway
3.0 ghz
1 gig ram
160 gig hd
XP Pro

Thanks in advance.

Did you setup on the Home Network using the Wizard First? Second did you check the firewalls to allow connection and 3rd are all the protocolls setup with your device?You say networking - how many pc's do you have CONNECTED?
Is it your dad's system that wont connect to the internet?
What error message does IE GIVE you when you try and connect?
Does the modem GET the adsl light lit ok?
Did you install the internet connection from the ISP's disc?
You mention in your list Gateway - are you using a broadband modem or router?

Is this a network or a dial up modem?   Quote
