OK, here is the problem. When I use Internet Explorer 6 to browse internet I receive error saying it can not open the page and on the bottom of the message DNS Error is written. Strange thing is I can surf internet with any other browser without the problem. What might cause such Internet Explorer behavior?
Considering that other browsers are working I would suspect that you have spyware on your system. Internet explorer is the most vulnerable on spyware threats in comparison to other browsers so it affects only him. Download anti spyware tool (there is many free solutions on the internet) and clean your system.
