I get the message "Unable to Connect" in both Firefox, Safari, and Opera when trying to go to the following websites: http://chris.pirillo.com http://www.equifax.com http://www.kmsstv.com It's weird because I can navigate to other pages, like this one, and google, facebook, amazon, you name it. I can get to the vast majority of sites, but I can't get to these three in OS X. (I'm running 10.4.11, but don't know if that has anything to do with it.) I've tried changing and checking my DNS settings, but they're fine. I even booted up in Windows XP to see if it was the external network of my ISP, and it went fine! The diagnostic assistant says my network connection is fine, and it is, except for these sites. Any ideas or suggestions? Thanks in advance.
