Thanks,

Linux - NMAP - normally installed with OS

NOTE:  NMAP is probably the best overall port scanner available.

And outside of that if you have linux machine running you could always ping the broadcast address.  Quick a dirty!

I've tried all of the programs above, and found out that Adrem NetCrunch does not have any competition.
Not only he's have the discover but it can show you the diagram of the connections (who is connect where).
Also a monitoring of ports and browsing the SMTP.
Great program.

Ostrosoft Network Tools (another freebie).

The "advanced" options under "ping" on Cisco IOS are often sufficient.
