Just recently, I have not been able to login to certain sites, such as GMail, Yahoo, or USBank. I thought I was having a problem with firefox, the error I get is "Firefox cannot establish a connection to the server at
www.google.com". I switched over to IE and had the same problem, the error I get here is the usual "This page cannot be displayed". I am able to login to other sites such as myspace. I thought this might be a problem with my router but I can access and login to these sites using my laptop which is connected wirelessly. I haven't changed any settings on my desktop.
Both systems are running Windows XP Pro.
