Problem accessing ebay and paypal

We are having a problem accessing these two sites. When you type the url in directly, it goes to "page not found" or a yahoo site search page. We can get in to these programs through a 'back door' (i.e. pulling up an item number directly), but cannot log in by using the www.ebay.com or www.paypal.com url.

We are running Windows XP Home Edition version 2002, service pack 2. My Internet explorer is Version 6.0.

I have a firewall running, but I still cannot access these sites even if I disable it. I have also tried to put the website url in the favorite or accepted list but they still do not come up.

Any Geek help will be greatly appreciated!
