This one’s got me REALLY stumped . . . Recently, and more often than not, I get the standard “Page cannot be displayed . . . Cannot find server or DNS error” Error page.
These are KNOWN OK sites. Minutes later I can get there from my Fedora system, immediately go back to Windows (XP Pro,fully patched, btw), and same old, same old.
Ive run Antivirus (AVG), Ad-Aware, SpyBot S&D, Hijack This, Stinger, CWShredder — nothing found.
I’m Running Zone alarm — I’ve adjusted rules & settings back, forth, to, and fro. No change. Disabled the firewall (briefly, of course!). Still no joy.
Hosts file shows loopback IP address ONLY.
Sockets files appear to be OK, and no dupes.
Cleared the browser cache, too.
No problem with the ISP or Cable modem (This particular Win XP pro system is the only one of several I administer, both at home and work, that is having this problem.)
As it’s impossible to provide a comprehensive list of sites I’m not getting to, here’s what doesn’t work so far:
Anything Microsoft (including MSN and Messenger login)
Tek-tips.com
any & all HTTPS sites (bank, & OWA to Exchange Server, for example) Yes-I checked security settings, and they’re correct per MS.
Several others too numerous to mention.
No problem with Google*, TechRepublic, Pogo, and other, less prominient sites (local newspapers, all .edu – so far- , etc.
*Unless, of course, I follow a google hit to one of the “broken” sites.
So, in a word — help. Any ideas out there?
