I am using a Mac Pro 2.66ghz x 4 with OS X 10.4.8 There are some websites that just won't load (including youtube.com so its not the sites fault) in any of my browsers. I have Firefox, Camino and Safari which are all experiencing the same unable to resolve the domain problem. I don't know enough about OS X or Unix to fix this, in Windows XP there is a chain of events in the registry called the Winsock which can be replaced to rid a machine of a problem like this. Is there a similar fix for resetting the chain of events for web connectivity on a Mac? I know there is no registry on a *nix OS but surely there is some fix for this problem. I NEED to be able to access the web, I do not want to spend the umpteen hours necessary to reinstall OS X.
