'The connection was reset' error only on certain websites

[ImagesAndWords]

I re-installed Windows XP SP3 fresh on the pc I'm currently using, but ever since then, certain websites are inaccessible. Firefox just tells me "The connection was reset" and IE and Chrome won't access them either.

The weird thing is:
- 99% of all other sites work
- These same sites work fine on all other computers in our home network. Same network, router, ip-range, subdomain, gateway, dns, etc.
- If I ping the URLs, I get "Destination net unreachable". All the working sites ping just fine
- Windows firewall is disabled
- Clearing private data like cache, cookies doesn't work

...the fuck?

are they on port 443 maybe?

also reset your modem / router maybe you have an ip conflict with something else on your network

I don't think so but I'm not sure. But wouldnt' this only matter if my Windows firewall was active?

Btw, I just reset them both but it made no difference.

Possible hosts file entry for those websites? Can you get an ip address returned if you run nslookup domainname.com from the command prompt?

I had this shit happen to me as well. My IP refused to load mandarin sites for some fucked up reason. Check to see if you have the urls listed in the win direct under the same access files that is using some sort of a local network. See if your localhost txt file is blocking these sites. It could be due to an offline server like wamp or something. That was my problem. I got it rectified.

Yeah nslookup returns the IP of the sites, but pinging those IPs gives me the same error as pining the domains: "Destination Host Unreachable"

Change your DNS servers. Try Level3 or Google's.

Also run a traceroute.

I was having the same issue and had to reconfigure my FF settings.

Go here; Firefox cannot load websites but other programs can

and follow the instructions to toggle the ipv6 settings. Worked for me.

I had the same problem about 6 months ago. I reinstalled my adsl modem drivers after messing around with it and it worked fine.

Install Win7 problem solved.

Have you got Malware Bytes installed? This sometimes blocks websites it doesn't like.

Have you checked the host file? Have you done a spyware check just in case?

It isn't going to be the router as it works on others.

Thanks to everyone who chimed in with suggestions!

That was it, so thank you! I disabled Malwarebytes' "website blocking" and it worked right away... shit.
