[Samba] Samba 3.5 loses local master browser election to Win7 32bits
Hi All:
I'm facing a weird behavior with Samba 3.5.10. It's a CentOS 6.3
repository RPM. Samba is acting as a PDC and integrated with OpenLDAP
2.4.23, also a CentOS RPM, through smbldap-tools 0.9.3 (from EPEL).
In my network I have Windows 7 64 bits and Windows 7 32 bits. The
problem is that Samba is losing local master browser 'status' to Win7
32 bits machines. From time to time, some Win7 32bit forces an
election and *wins* ! :( But I'm using os level 255!!!!
At startup, nmbd forces an election and wins. Then some machines tries
forces an election.. they looses for a while then after some time
(say, one day to other), nmbd seems to give up and loses master
browser 'status' :(
The interesting fact is that Win7 64 bits seems not forcing/winning elections.
my config (relevant part):
workgroup = XXXX
netbios name = PDC01
interfaces = eth0 10.6.
bind interfaces only = yes
hosts allow = 127. 10.6.
[...]
security = user
passdb backend = ldapsam:ldap://ldapsrv.xxxx.com/
ldap suffix = ou=rec,o=xxx
ldap ssl = start_tls
ldap admin dn = cn=admin,ou=rec,o=xxx
ldap passwd sync = yes
ldap delete dn = yes
ldap user suffix = ou=users
ldap group suffix = ou=groups
ldap machine suffix = ou=computers
domain master = yes
domain logons = yes
[... smbldaptools scripts ...]
os level = 255
preferred master = yes
local master = yes
wins support = yes
time server = yes
Now I've increased nmbd's debug level to 2 to see if I get some clue.
Any help ??
thanks a lot in advance

[Samba] Samba 3.5 loses local master browser election to Win7 32bits
The Win 7 x32 clients are configured to use a Wins server? I am assuming you have this pushed out via DHCP? Maybe it is something unique to a batch of computers that just happen to be running x32 vs x64? Apart from x32 vs x64 OS versions, is there any difference between the x32 and x64 machines? Windows firewall settings? Do things like ipconfig and nbtstat show different results on the x32 vs x64 machines?

i suggest you try also set preferred master = Yes and/or increase the os level in global smb.conf like. os level = 65 greetz, Louis>-----Oorspronkelijk bericht----- >Van: lucas.brasilino at gmail.com >[mailto:samba-bounces at lists.samba.org] Namens Lucas Brasilino >Verzonden: dinsdag 29 april 2014 19:44 >Aan: samba at lists.samba.org >Onderwerp: [Samba] Samba 3.5 loses local master browser >election to Win7 32bits > >Hi All: > >I'm facing a weird behavior with Samba 3.5.10.
