Internet Explorer 6 will not access online streaming radio

[oreodog]

Hello again, Old problem different computer. I have a Dell XPS 400, 2.8 dual core, 2 G RAM, SB Audigy, Norton with all firewalls shut down and 250 G HD, I am unable to access online radio stations in IE and Firefox. The station comes up "the page cannot be displayed". It has the extension .asx usually. In IE, most of the time, I am unable to open a seperate page from a link on a website not in Firefox. I am getting sick n tired of Dell's XPS tech line. This has gone on since I first started the computer. Any help will be greatly appreciated. Thanks, Dog
