Oh, Hubris, thy name is Yer Mamma. Yesterday I couldn't get one of my computers to send a file over wireless to another which had the right printer attached. So I tried the laptop instead. Then someone else's laptop. Then started fiddling with firewalls. Then started passing from A --> B to try to get to C. Then finally went and checked the unreachable computer after an hour of this. Its connection had dropped. L.
