The problem which I am having and have had for the past 6 months(since I upgraded my computer and reinstalled XP) is that certain sites for an unknown(to me) reason don't load. Almost every single website I go to DOES load perfectly fine, but a select few don't. Examples of these sites include www.nsa.gov www.pcmag.com www.space.com Now, I know that it is not a problem with my isp because all other computers in my house do not have this problem. Here is the error I receive when attempting to visit www.nsa.gov This is also not a browser specific problem. This problem persists in firefox(my main browser) and I.E. I have tried to disable my firewall, enable ALL cookies, etc... Nothing has worked, I am completely stumped as to why this occurs. If anyone can help, I would be very thankful.
