[Samba] Advanced server config question

[Fred]

Greetings,

I have an advanced config question that I'm hoping the Samba Gods can 
help me with in regards to feasibility and execution.  I'll give the 
concept of what I want to do, followed by the details of my present 
config.

I have a functioning samba 3.0.8pre2 server that is multihomed.  The 
100Mb line is attached to our main network. the 1Gb line is attached to 
a private 1Gb lan used for backing up our file servers.  It is a member 
server in a W2k3 Active directory domain and its working fine.

This is the directory structure of the data being shared, the samba 
shares are defined on the eng, prod, and ext levels on the primary 
100Mb interface.

/data/shares/eng
/data/shares/prod
/data/shares/ext

This is what I would like to do.

   I would like to keep the shares already defined intact sharing out 
on the 100Mb lan

   I would like to share to the private 1Gb lan because we have 
started to use a near-online backup strategy using a dir-sync tool.  we 
do a basic copy with ntfs permissions from the file servers to the 
backup server's array, from this array, we create the backup tapes.  

so far so good.

   I would like to share the file system at the /data/shares level for 
backup simplicity, but i'm aware that it might not be possible to share 
at that level because there are subordinate directories already shared.

   This part is a little more important.  The machine is registering 
itself in wins; registering the various services and names as its 
supposed to. is there a way to prevent the server from registering the 
server's 1Gb private lan shares in wins on the primary interface?  and 
if so,  how do I do it?

    My concern is that if I share out to the secondary 1Gb private 
lan, and it registers itself in wins, that our client machines won't be 
able to resolve the server sometimes because the client on the main 
network recieved the 192.168.0.x address from wins.

is this setup feasible? what are my options? and how do I go about 
setting this up?

below, I will provide my smb.conf

Regards

Fred Dussault

also,  if there are any glaring mistakes in my config, I'll appreciate 
any constructive criticism...   Thanks!
