How are you scanning by ip? What program if any or did you write a script? To answer the main question, no xp isn't invisible by default at least.

I doubt that it's invisible.. For some reason, I just have the feeling that you're trying to use Cain and Abel. If XP is stationary, then it may be dependent on how to setup is. If that computer is routed through the router, then you will see his IP there. I know, I've done it before. If it's routed straight into the cable, rather than through a router, then you probably won't be seeing his computer on a router that he isn't connected to.
