rogue IP address

[<dondon () pacbell net>]

Someone on our network assigned an IP address to their own system without 
my knowledge.  Using LANguard network scanner, the best I can tell is that 
it's a Linux box.  The port-to-IP mapping table on our Asante switch 
doesn't see to work correctly.

Any suggestions on tracing down that system that is associated with the IP 
is appreciated!
