Hello list
How can I manually register a server in a Samba Wins Server ?
I'm facing this scenario
firewalled net
in the DMZ    Samba Box 3.0.25    FreeBsd 6
In the NET    Windows 2003 SP1
The samba box is authenticating user against the Windows 2003 server. Of
course the firewall is open for TCP 445 88 137-139 UDP 137-139
problems pop up for all NET RPC comands
the samba box cannot find a Domain Server.
Obviously it is because the firewall is stopping broadcasts from DMZ to
So I made Samba working as WINS server
the problem is this
The Domain server WILL NEVER try to register on the Samba Wins Server
and I'm not willing to open Intranet to DMZ WINS comunications over the
I'd rather preferr to register MANUALLY and ONCE the Windows2003 server on
the Samba WINS server.
How can I do this ?
I searched over and over in google, but found no clue at all.
