Yes...yes there is.  I free little utility known as Look@Lan.

Pretty cool util for being free.  You can set it up so that it scans an entire
subnet every x minutes.  It will notify you when an new IP comes online or goes
offline.

Its a bit buggy under NT, but works great under 2000.

Hope that helps.

Subject:  Network scanning



Are there tools out there that would allow system administrators to be
notified when a new workstation attaches to a network?  I'm thinking both
wireless and ethernet in this case.  SNMP maybe?  I am in a credit union
environment and my concern is that someone would be able to steal an
existing jack or a jack that is not physically protected but live and be
able to capture traffic or do reconaissance.  We don't have Wireless access
at this point but may look to it in the future.  My only thought in that
case would be to encrypt all traffic since wireless security is a bit scary
at this point.  Any ideas?
