I just read through this article about different types of users and how to deal with them.  The article didn’t really give much solid advice since it was mostly opinions from a bunch of different IT people who had their own ideas about the problem.  It really all came down to managers saying something like “don’t lose your temper.”

But this one paragraph about the “know-it-all” user struck me:

You know this user. He knows a little HTML, and he defragged his hard drive once, so now he thinks he’s an engineer who knows more than you. He often refuses to follow policies and instructions and has been known to poke his head in the server room “just to see what you’re up to.”

Ummmm, if a user can “poke his head in the server room”, then you might need to think about security.
