[Samba] Trouble finding all smb shares on network

Hi, just joined the list and know very little about smb.

I'm trying to do something that should be simple, but my current  
solution isn't working 100%

All I need is a list of smb shares on the network.

I'm doing this:

/usr/bin/nmblookup -M -- -

and then use this on each ip returned:

/usr/bin/smbclient -g -p 139 -NL <ip addr>

That works for most cases but it fails to find all the shares  
(compared to the mac Finder)

I asked Apple developer tech support to help, but they don't want to  
give me the complete solution.  There seems to be some additional  
things I need to do to ensure that I find every smb share.

So, according to Apple, there is some secret alternate method of  
calling nmblookup to get the real list of shares, but they won't tell  
me what it is.

Please give me a hint, point me to docs or something. I'm on a mac and  
just want to get the same list displayed in the Finders "Shared"  
section of the sidebar.
