Sometime when I'm trying to get to the bottom of an issue when the user is a programmer I get surprised when I find a gap in their knowledge - like today when I realised I was asking questions about probable DNS issues to a guy who really had no idea how DNS worked.
I don't mean he SHOULD have known, there's no reason for him to be, but I sometimes forget that "IT" is a pretty broad field and I've been in it longer than some of these guys have been alive. #sysadmin
