Hy !

Every few seconds I get the following note in my /var/log/warn

-------------------------------------

Jun 9 10:15:06 xx nmbd[27058]: *****
Jun 9 10:15:06 xx nmbd[27058]:
Jun 9 10:15:06 xx nmbd[27058]: Samba name server xx is now a local master browser for workgroup xxx on subnet xx.xx.xx.xx
Jun 9 10:15:06 xx nmbd[27058]:
Jun 9 10:15:06 xx nmbd[27058]: *****

-------------------------------------

my smb.conf

-------------------------------------

[global]
netbios name = xx
workgroup = xxx
security = domain
domain master = yes
domain logons = yes
prefered master = yes
name resolve order = wins lmhosts hosts bcast
os level = 255
time server = no
unix extensions = Yes
encrypt passwords = Yes
map to guest = Bad User
-------------------------------------

we also have a bdc which has os level 254...

Any ideas ?

Thats errors can be a signal that a Domain Controller of the network already exists (like a WinNT Server, or similar), and Samba´s detects the presence of this servers and deactivate the Prefered master option.

If you do not plan to use Samba´s services to manage the network, I recommend disable the Prefered Master option:

in smb.conf
domain master = no
prefered master = no

Good luck!
