samba - Aug 2011 - Basic network discovery on a microcontroller?

Hi,

I have a general Samba question I'm hoping someone can help me with. I'm
working on a network device which I would like to make network discoverable, so
that you can open up "Network Places" on Windows and see the device
there. The project has a microcontroller with a full TCP/IP stack, but no
SMB/CIFS library. I'm guessing I only need a small subset of this
functionality to send out a discovery broadcast--can anyone give me any pointers
on whether this is possible or where I could get started?

Best,
Tom McLaughlin
