the strangest things happen with internet issues when your Internet Preferences get corrupted.
if all of your browsers have the same problem, likely you need to delete your Internet Preferences and restart and reset them.
Once reset, it might be a good idea to make a copy of the Internet Pref's file and keep it handy...
and oh yes, MacTCP DNR is a troublesome file... it sometimes needs to be deleted... upon restart MacOS will generate a new copy of it. (if not, then get a copy of it from your MacOS CD's System Folder)
