[Samba] Primard Domain Controller feature not working

[Mark Ratering]

Hey guys,

I configured Samba do be the domain controller for my network and to
share folders.  the folder sharing works great.  The problem is that
the domain function does not work at all.  I cannot join the domain
from any workstation.  It just says that the controller cannot be
contacted.  I ran an Ethereal sniff on the packets and the computer
that i want to be PDC is sending ICMP Destination unreachable packets
in response to the NBNS Name Query.  Here is the packet that the
workstation is sending to the server.

The config file that i am using (not including shares that have
nothing to do with the domain controller).  I do not want roaming
profiles.

        #NetBIOS settings
        netbios name            =       FILESERVER
        workgroup               =       USBINGO
        server string           =       File Server

        log file                =       /var/log/samba/log.%m
        max log size            =       50
        time server             =       yes
        hide dot files          =       yes
        log level               =       1

        #Security settings
        security                =       user
        domain logons           =       yes
        encrypt passwords       =       yes

        #Turn on the WINS server
        wins support            =       yes

        #Make sure that Samba is the master browser and domain master browser
        domain master           =       yes
        local master            =       yes
        preferred master         =       yes
        os level                =       65

        add user script         =       /usr/sbin/useradd -d /dev/null
-g 100 -s /bin/false -M %u

[netlogon]
        path                    =       /files/netlogon
        writable                =       no
        browsable               =       no
