All you would have to do is open a sniffing program such as tcpdump or
ethereal (i would think there are similar windows products, maybe not
though) and contact the host. From there you can dissect the packet and get
the information.

I have a question regarding the recent discussion about IP to MAC mapping.
In fact suppose you have a system installed which controls if any unknown
MAC address exists in your lan.
There would still be the possibility to replace an official workstation by
a laptop with a reconfigured MAC address
gHND "Adding $array[0]\n" if $ARGV[1] ne silent;
$list{$array[0]} = $array[3];
}}
}
close(FileHND);
sleep 3;
}

username, OS, shares, open ports, Security Alerts, drives, processes,

Understand that most OSes (perhaps not windows, but I wouldn't put it past
having a registry key somewhere) allow you to set the MAC address to
anything you want it to be... So all you would find would be casual
crashers...
Set up a small Linux or *nix box and use arpwatch - it's a daemon that
