Well, it would seem to me that if it has an unknown address on your
network, you've already spotted it.  You would really need something
like nmap to make a stab at what type of OS is running on it.

There is another tool for fingerprinting, that often does a better job
than nmap. Check out http://www.sys-security.com/html/projects/X.html.
Impressive stack analysis!

xprobe has better depth than nmap on the Microsoft stacks but doesn't 
have anything like the breadth of coverage for different operating 
systems. It might be interesting to write a script which uses several of 
the available tools to double-check any guesses.

Hold off your breath until the next release of xprobe. :-) Additionally
there're some people working on incorporating xprobe and nmap
fingerprinting techniques into a single tool. When it comes out, it
might be really interesting :-)
