Hi, brothers, frineds and people


yaar I have some prob with my samba configuration I have some multipale 
networks I have configured samba on one interface when i try from some 
other interface or network it gives me a errot that domain is not 
found. I am runing samba as a PDC on my network with one interface it 
works fine and when I try the other one it doesn't I have changed 
following lines many times in smb.conf

interface= 172.168.0.0/24 172.168.1.0/24 as extra

I have tried this one also 

interface= etho
 
I have tried this one also 

interface 172.168.0.0 netmask 255.255.255.0 172.168.1.0 netmask 
255.255.255.0

but none of them works I am really worry about it because I have to 
start my network as soon as possible.

help will be really admireable and thanks in advance if some one will 
take me out from this prob.
