Well written Whiz.......I have a quick story to tell on this topic. My company is going to be giving a training tomorrow in an office building that isn't ours. We called the receptionist today to ask if we could come in and make sure our software could get out through their firewall. She said to come on down and didn't even ask who we were or what company we worked for. I went in with my laptop and she showed me to a place where I could plug into their ethernet. I was immediatly given an IP and had access to every node on their network simply through "my network places." I could have been anyone and she believed everything I said with no questions asked. Funy isn't it?
