Problem establishing connections with certain sites

[moose]

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[/url] [url]www.pcmag.com[/url] [url]www.space.com[/URL]

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 [PLAIN]www.nsa.gov[/URL]

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.

Hmmm I had a similar problem with search engines and it just turned out i needed to remove some spyware, my other rememdy before I readlized I had spyware installed that somehow disable certain connections was the following. In internet explorer do this:

- Click on Tools
- Internet Options...
- Click The Advanced Tab
- Under Browsing Uncheck The Box That Says "Enable 3rd Party Browser Extensions"

If that doesn't work I suggest downloading, updating, and running both Adaware and Spybot S&D

If that doesn't work and you are using a router, I suggest resetting the router to its default settings, the router may be blocking communications on a certain port under one of the computers locally assigned IPs.

If that doesn't work then I have no idea how to fix it other than backing all your documents up and reinstalling windows.

Thanks for the reply,
That did not work and I already run Adaware and Spybot from time to time.

If that doesn't work and you are using a router, I suggest resetting the router to its default settings, the router may be blocking communications on a certain port under one of the computers locally assigned IPs.

I could try that, and how would I actually set it to the default settings? Do I have to hard reset?

If that doesn't work then I have no idea how to fix it other than backing all your documents up and reinstalling windows.

Meh, I hope it won't come to that...I might reinstall linux to see if it works there or not.

have u checked your host file?

Could you elaborate on that? I don't really know what you're talking about...

dns name resolution works like this:

when you type a URL into your browser, the first thing your PC checks for a name to IP resolution is your local host file.
if no entry is found there then it checks the dns server that is found in your tcp/ip config... (its a lot more complicated actually buts that's the essesence)

For XP open notepad, then with windows exp go to \WINDOWS\SYSTEM32\DRIVERS\ETC

drag the file called hosts to notepad, typically it shouldn't have any entries apart from the localhost (127.0.0.1) if you have other entries there and you didnt put them in remove them as they were probably introduced by some malware.

For Linux at cli do a:

vi /etc/hosts

and check for the same stuff as xp

Anttech, localhost was the only entry in the hosts file :*(

I don't understand why this problem occurs, I wonder what these sites(which I can't reach) have in common...
I will search through some forums some more to see if anyone has had this happen to them.

do a tracert www.nsa.gov[/URL] and see where it fails... Perhaps your ISP is having some routing issues

Ok, I did that and I just sent you a PM with a screenshot of what it came up with.

yeh... Saw it, seems ok, as I get the same when doing a tracert... I don't think there are any network problems

I just moved my computer to a different room and connected it to a different cable and it still doesn't work, so this is definitely a windows problem. I just don't understand what it is that isn't letting me go there. I don't have any parental controls or any of that crap.
