Cannot find server or DNS Error?

[user22]

I am using windows xo pro sp1. When I am on a site I need to stay on and click refresh IE6 will work for awhile and then it will go to page cannot be displayed, at the bottom is cannot find server or dns error. I thought at first something was corrupt, so I reformatted and installed the same os. It started this again before any programs were reinstalled. When it does this I can close that page and try and reopen IE6 but I get the same error. The only way it will work is to reboot and everything goes along fine for a little while, then I get the error. I can't even log off and log back in again to get it to work. I know my connection to the internet is okay, because I can still get mail in and msn messenger is working fine, just IE6 has died.
Does anyone know what is causing this or how to sure it?

If you wish to use HijackThis to troubleshoot an issue, please read the sticky thread in the Security forum. There are things you need to do first (scan for malware, etc.) and HJT needs to be run immediately after a fresh reboot with no other programs running.

As for your log, I see a couple things that don't look quite right - you need to do some scans.
