This one's peculiar: I'm trying to reach a particular website, www.quixtar.com. The site is a virtual mall with both http and https pages. For example, "http://www.quixtar.com" will NOT load, but "https://www.quixtar.com" pages will load the login-in page just fine. But if I log-in, then any pages within the site that DON'T require https:// prefix still won't load.

I've tried every trick I've read, such as flushing the DNS on my computer, releasing the IP address, reinstalling windows, etc., with no luck. Also, I have another computer in the house that shares the same DSL internet connection and modem, and it works just fine, even though it broadcasts the same IP address, so I know the site isn't restricting my computer for some reason.

Any thoughts?
