I'm working on a Windows XP Media Center computer that seems to be having difficulty accessing web pages...specifically scripted pages. As an example, from Internet Explorer 6.0 if I try to access the webmail from comcast.net: http://www.comcast.net/qry/goto?app=mail&CM.src=top where there is a ? in the address
it will immediately go to page not found saying that it can not connect to the specified page. I have made sure that I have SSL and TLS selected in the options, I have turned off the pop-up blocker and uninstalled all antivirus and firewalling software. I have also tried installing Firefox to see if this works however firefox will not access any webpages at all nevermind the ones that IE is having issues with. I am using DHCP and am getting an IP address without an issue and can obviously see the internet since I can visit some webpages in IE.

Does anyone have any idea? I am running out of options besides from reformatting.

Thank you,
Dave
