Problems with web surfing

[RandomPING]

My computer was doing fine till a couple of days ago, then I installed some updates and got rid of some spyware, and then it was running great. But the problem started when i tried to access some sites that were a little "off the beaten trail" as it were. A lot of the slightly less popluar sites that i could access days earlier were now giving me "Page can not be displayed" or "page can not be found" errors.

I think i've heard of this problem before, but i can't figure out just where. I can suprisingly still access this site, yet not netscape. I tried installing "Opera" and got the same problems with a lot of the pages. Has anyone ever seen this problem before, does anyone know a solution? I'd do a websearch myself, but most websites come up with that error when i actually try to visit them, it's very strange.

Any help would be apreciated.

I'm running:
Windows 2000 Pro (all critical updates installed)
800 Mhz
130 MB Ram
On board sound and graphics. (don't think they're the problem anyway)

I tried that, even tried resetting the permissions and the protections. I'm thinking maybe i should set it up to go through a proxy to access the pages, because it's like the physical path to some servers is just cut off, but i can go around it with accessing things remotely.

This isn't my system really, it's my friends system that he just uses for the internet and typing, these sad sad specs are not of my system (not like anyone really cares, but I still wanna set the record straight).

I'm thinking if worse comes to worse, i'll bring my computer over there to see if it's just a network issue. And if it isn't, then i'll have to reinstall windows and go through and check all the service packs one by one to see which one to go up to before it hits problems. I'm pretty sure that's the cause, though it's strange that some sites work and others don't. Like half the internet is down.

Sounds like DNS issues to me. You could try switching to other DNS servers, or checking whether the ones currently used are the right ones. Info about it like DNS server IPs should be on the provider's site.

If it's not DNS, it's probably still not an issue on your side of things. Because you can reach the internet, what happens after that is in the provider's hands.

I could, of course, be wrong though

As GreenBunny suggested, it sounds like a DNS issue. Try flushing your DNS cache

Start > Run > cmd
type in ipconfig -flushdns
