Hi, I've been having trouble connecting to the internet on one of my older computers for a while and I need some help. It's the only computer on my network of 3 (run through a 3COM OfficeConnect Router model: 3CR858-91) that can't connect to the internet. I've tried messing with dynamic and static IP addresses, checking all my cables and my network card (they all work), and pinging websites brings back a positive response.  Every browser i use though doesn't display anything, like they can't even connect to the web (Firefox just has an "Untitled" as the page name and nothing comes up). I don't know what to do at this point and I need a second opinion on what to do. Thanks.

Intel Q6600 (Core 2 Quad CPU 2.4 GHz)

Do you have the latest drivers installed for your NIC? I ask this because XP's service pack 3 had issues with some cards.

You should also check your DNS settings on the machine--maybe try Google DNS.  And check that your Hosts file isn't corrupt.

Figured it out, turns out there was a LSP problem. Thanks for the help.

That kind of malware can sometimes be a real PITA to remove completely without compromising or hosing the system.
