samba - Feb 2004 - second samba server in my lan do not work

Hello,

I have a problem with my samba-server running in a VirtualServer
(http://user-mode-linux.sourceforge.net/).

                            Internet
                               |
.------------------------------|-----.
| LinuxHost                    |     |
|                     eth1=80.x.x.x  |
| .---------------------.      |     |
| | VirtualServer (UML) |      |     |
| | eth0=192.168.0.111  | <iptables> |
| '----|----------------'      |     |
|      |                       |     |
|     tap0 = 192.168.0.254 = eth0    |
'------------------------------|-----|            .-------------------.
                             \ | /                | eth0=192.168.0.53 |
                        - ----LAN-----------------| Windows-Client    |
                             / | \                '-------------------'
                    .----------|---------.
                    | eth0=192.168.0.160 |        
                    | LinuxPC            |
                    '--------------------'

I can access the shares of the VirtualServer from the LinuxPC by using
his name or his IP.
  mount -t smbfs //VirtualServer/Video /mnt/disk
will also work as
  mount -t smbfs //192.168.0.111/Video /mnt/disk

I can access the shares of the VirtualServer from Windows-Client only by
using his IP.
  net use X: \\192.168.0.111\Video /YES
will work, but
  net use X: \\VirtualServer\Video /YES
will not work.

Both, "net view" in the dos-box of a window-PC and "nmblookup -d
2 '*'" out
of a linux-box will show all win and linux/samba-PCs in my LAN but not the
VirtualServer.

Also smbclient seems to indicate strange results:

[LinuxPC]# smbclient -NL LinuxPC

        PRIVATELAN           VIRTUALSERVER

Both seems to be the master-server? Why?

My smb.conf in VirtualServer:
[global]
        workgroup = PRIVATELAN
        netbios name = VIRTUALSERVER
        server string = Samba Server %v
#
# Security
        security = user
        map to guest = Bad User
        encrypt passwords = Yes
        username map = /etc/samba/smbusers
        unix password sync = Yes
        hosts allow = 192.168.0.0/255.255.255.0
#
# Domain-Management
        os level = 65
        preferred master = yes
        domain master = yes
#
# WINS_Server
        wins proxy = No
#
# should work as WINS-Server
#       wins support = Yes
#       dns proxy = Yes
#       local master = Yes
#       name resolve order = wins lmhosts hosts bcast
#
# should not work as WINS-Server
        wins support = No

and the same within the LinuxPC:
[global]
#
        workgroup = PRIVATELAN
        netbios name = ATHLUX
        server string = Samba Server %v
#
# Security
        security = user
        map to guest = Bad User
        encrypt passwords = Yes
        username map = /etc/samba/smbusers
        unix password sync = Yes
        hosts allow = 192.168.0.0/255.255.255.0
#
# Support Net-Logon
        logon script = logon.bat
        logon home = \\%N\%U\profile
        domain logons = Yes
#
# Domain-Management
        os level = 64
        preferred master = No
        domain master = No
#
# WINS_Server
        wins proxy = No
# should work as WINS-Server
#       wins support = Yes
#       dns proxy = Yes
#       local master = Yes
#       name resolve order = wins lmhosts hosts bcast
#
# should not work as WINS-Server
        wins support = No
#       wins server = 192.168.0.x


Is it a problem with the smb.conf or the network configuration?
Or maybee with iptables? I have IPCop on the LinuxHost wich firewall is
designed to block most of eth1 (the external interface) and allow all on
eth0 (the internalinterface)

Another samba-server can be fully reached from all PCs in the LAN.

Now I have configured the SAMBA-Server on VirtualServer as Primary Domain
Controler and as WINS-Server:
        domain master = Yes
        local master = Yes
        preferred master = yes
        os level = 65
        wins support = Yes
All other SAMBA-Server in the net would be configured as no PDC and also no
WINS-Server but to syncronized with the WINS-Server:
        domain master = no
        local master = Yes
        preferred master = yes
        os level = 65
        wins support = No
        wins server = VirtualServer
The DHCP-Server has to deliver not only the IP-Adress but also the adress of
DNS-Server (option domain-name-servers <ip-adress>) and the adress of the
WINS-Server (option netbios-name-servers <ip-adress>).

What should I say ;-)
It work.
