dnserror

I’m working on a Windows Me system in which I have just replaced a modem. Now I get “Page Cannot be Displayed” error when attempting to log on to any URL. I have gone through most every procedure recommended by Microsoft and still cannot make it work. Have installed IE6 SP1 and removed all remnants of AOL (except Instant Messenger). Checked for presence of Gator, Bonzi’s InternetBoost and other maverick apps. Still not working. Help or I will need Rogaine soon.
