This makes it impossible to tell where the login is from. >How-To-Repeat: I'm not quite sure -- I don't know why I am getting an entire domain as invalid, but I've seen it happen a couple of times. Once is when I set up a PPP connection to work, in addition to my standard internet connection; this results in, I think, an inability to talk correctly to the nameserver for the domain. I've also seen it happen when the primary nameserver for a different domain was having network troubles, and was unroutable. >Fix:
