Say, for the sake of argument, that I'm sitting at my Mac and I click on the Network icon and find a "JohnNorris" on my network. Say too that I am curious. Let's further hypothesise that I click on Connect, it asks for a password, and, just for the hell of it, I type in "norris". Hey, it worked! I appear to have full access to someone's Windows machine: it's asking me whether I want to connect to his C drive or "Billenden". In the C drive are all his iTunes mp3s, many, many photographs of children, and a slightly suspect video or two. I could just drag all this stuff off his drive, I suppose. But instead, I placed an rtf document on his drive saying "Hi, John Norris. You are on my network." What might anyone here do in this situation?
