If you have both XP & Norton firewalls then disable XP FW but configure Norton to allow LW full access; * Configuring Norton Internet Security

r8rfan1010 should see this: Did you configure your firewall so it allows LW full access (advisable not to have 2 active firewalls b/c they can interfere with each other); Firewall configuration instructions (click on link)

Can you both tell us what are your Modem & router brand name & model numbers? I suspect this is the major issue here. Your connection devices have NAT firewalls & either need UPnP activated or else, need to be manually port forwarded. We need to know what you're using before we can advise more about it.
