Samba cannot find my workgroup on subnet UNICAST_SUBNET

I've got a samba server that has

Code:

workgroup = NTDOMAIN

and when I change this to

Code:

workgroup = ADDOMAIN

I end up with loads of the following spewing all over my logs

Code:

nmbd[5127]: [2006/12/15 17:23:15, 0] nmbd/nmbd_browsesync.c:collect_all_workgroup_names_from_wins_server(588)

nmbd[5127]:  collect_all_workgroup_names_from_wins_server:

nmbd[5127]:  Cannot find my workgroup DOMAINNAME on subnet UNICAST_SUBNET.

I have another machine, almost identical in both hardware and software (I ghosted it) which I have set this to the new domain and it is fine with this. No errors in logs. The only difference is that the former is acting as a WINS server and has the following set

Code:

wins support = yes

I have tried things like

Code:

domain master = yes

and

Code:

domain master = no

but neither seem to make a difference.

I'm not sure why the WINS server doesn't just let itself continue as before. It is the WINS server after all and should query itself, but it is also on the same subnet as the Windows 2003 AD domain controllers so broadcast on subnet should also work. It just don't understand what' wrong with it.

Any Ideas?

Try to disable the firewall in this machine.
The default configuration in several distros blocks broadcast and/or the Microsoft netbios, wins, etc.

If disabling the firewall works, you can try to open some of theses ports and broadcast.

Code:

miguel@babylon5:~> grep -iE "^netbios|Microsoft-DS|wins" /etc/services | grep -vEi "^#|winsock"

netbios-ns      137/tcp    # NETBIOS Name Service

netbios-ns      137/udp    # NETBIOS Name Service

netbios-dgm    138/tcp    # NETBIOS Datagram Service

netbios-dgm    138/udp    # NETBIOS Datagram Service

netbios-ssn    139/tcp    # NETBIOS Session Service

netbios-ssn    139/udp    # NETBIOS Session Service

microsoft-ds    445/tcp    # Microsoft-DS

microsoft-ds    445/udp    # Microsoft-DS

wins            1512/tcp    # Microsoft's Windows Internet Name Service

wins            1512/udp    # Microsoft's Windows Internet Name Service

winshadow      3261/tcp  # winShadow

winshadow      3261/udp  # winShadow

winshadow-hd    3861/tcp  # winShadow Host Discovery

there is no firewall on this distro.
