Indeed .... every Tom, Dick and Harry is named Dave!
Funny enough I used to maintain a Novell server with 3 network cards in it, all 3Com. One was named Tom, the other Dick and the third Harry. Only showed in the log files, not on the user logins. I had most of the users on tom and Dick, using coax, and harry was the high speed 10/100M new ethernet we were transitioning to, with some 10M hubs for the new network. Switches were too expensive at the time so hubs it was, still have some around for the utility they provide for certain applications.
