I have a strange problem with one of our computers, the machine is running Windows XP and bascially IE8 kept crashing because of a problem with 'ntdll.dll', so I disabled all IE add-ons. ran ccleaner, uninstalled Norton AV (license had expired) and reinstalled AVG. Basically now I am unable to hit any webpages by domain name or IP, the page just comes up with 'page cannot be displayed' I have installed Firefox but still the same problem.
Here's the part that is confusing me! I can ping internal network IP's as well as WAN IP's, google, bbc etc. I can also do nslookups no problem. I've tried after disabling firewall, no good. tried flushing dns, still no good. I have tried telnetting to a site on port 80 and connected fine and I am also able to log into msn messenger! I'm totally lost now so any help help/guidance etc would be gratefully received.
The only explanation I can think of is a virus (Apologies if I' should have posted in the malware forums but I thought I'd rule out a network issue first)
Many thanks in advance
