RE: locate windows workstation if you know the username

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.

Subject: locate windows workstation if you know the username


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.
