I am running 10.6.6 and I am having problems resolving DNS within any web browser, I have tried Firefox, Chrome, and Safari. From Terminal I can resolve DNS just fine. I have tried using my home ISP's, work ISP's, Level3, and OpenDNS servers, none have worked. I have tried renaming my Network Location, I have renamed various .plist files under /Library/Preferences/SystemConfiguration/ including Preferences and NetworkInterfaces. I also run a couple Parallels VM's they are not having any problems resolving DNS. I'm running out of ideas, here, any other suggestions?
