WG: WG: [Samba] Strange!!! Clients only log on to samba bdc

When I stop the BDC all clients log on to the PDC. And to my confusion
when I restarted the BDC today and made a testparm on both PDC and BDC
both showd role domain pdc --> Server role: ROLE_DOMAIN_PDC

Here my smb.confs:

PDC:
 [global]
	   security=user
        smb ports = 139
        logon script = logon.bat
        logon path = \\%L\%U\profile\%U
        logon drive = S:
        domain logons = Yes
        os level = 254
        preferred master = Yes
        domain master = Yes
        wins server = 192.168.135.150 #this is a smbd4wins server
running on 							the same
machine
BDC:

[global]
	    security=user
        smb ports = 139
        logon script = logon.bat
        logon path = \\%L\%U\profile\%U
        logon drive = S:
        domain logons = Yes
        os level = 65
        preferred master = Yes
        domain master = No
        wins server = 192.168.135.150

The way I understand it, workstations will use what ever DC is
"closest"

to them. If the PDC is taking longer to respond or something then they 
may consider the BDC to be the best choice.

WG: WG: [Samba] Strange!!! Clients only log on to samba bdc

Ist there no one concerning this behaviour?
I did my setup following the man pages.
There must be a serious bug in samba 3.031.

WG: WG: [Samba] Strange!!! Clients only log on to samba bdc

This is the strange thing I have set on the BDC

Security=user
Domain logons=yes
Domain master= no <--- not yes!!!
Os level=190
Preferred master=no

And when I do a testparm it results Role Domain PDC???!!

As I understand it, clients will prefer logging on to a BDC over a PDC,
and then use whichever responds quickest, so certainly all the clients
should not be logging in to one box or other - and probably least likely
to log on to the PDC of the two options.

I know that we see about a 60/40 split logins to BDC/PDC.

I don't think you should have domain master = yes set on the BDC.

Here's the settings from my BDC

[global]
        netbios name = CORE02
        server string = Longhill BDC (%v,%h)
        workgroup = LONGHILL
        interfaces = 10.108.1.8/255.255.255.0
        name resolve order = host bcast wins
        os level = 65
        domain master = no
        domain logons = yes
        local master = no
        preferred master = no
        guest ok = yes
        wins server = 10.108.1.32

Hope that helps

Can you post again exactly the global section from both PDC and BDC.
Several other settings have changed between your two posts which makes
it impossible to know exactly what the situation is!

Thanks
