Reverse engineering application protocol

[eddie]

Hi Guys,
Could anyone point me in the right direction - I would like to
intercept the messaging being passed between two computers on my local
network, and from the data captured reverse engineer the protocol the
two applications use to 'communicate'. The two devices communicate over
a NetBeui(sp) (Net-Bios snn) connection. I am assuming a Client-Server
architecture. I would like to be able to (ultimately) place my own
client on the network and successfully 'communicate' with the server
using the reverse engineered protocol. Can anyone suggest a tool or
analyzer that could help me?
Thanks,
Eddie

Make sure you're not connecting via a switch.
