ip.

on Unix nbtscan/nbtstat will do something like this.  It dumps the machine
name, username, domain/workgroup and MAC address.  I used to run it daily
and archive the output to see where users normaly logon.  The one I used
was written in C.  I had to add an alarm to it so it would timeout for
host not responding.

For the terminally lazy, you might Google TCPNetView. This GUI utility will give you both the IP address and MAC 
address.

Hello,

if they're using WINS, send a NetBIOS name
request for the username, netbios service 03
(i.e. messenger service) to the WINS server.
It will respond with the IP of the host registered
to the user's workstation.

Greetings fellow pen-testers,

Looking for ideas on tracking down a windows workstation if you know the
username.

I know that if I run     net send username ""     I can tell that the user
is online without the message box popping up on their machine (usually),
but
I'd like to know which workstation a particular user is at for a targeted
arp spoofing attack against a client.
