Description spurnelle 2004-06-07 01:18:18 UTC
Yesterday (06/06/2004) nmbd hs been crached because a WIN XP laptop tree to
force a election for master browser.

This laptop is connected to my PDC (samba 3.0.4), but there are 4 laptop with
the same win xp, all connected on my domain.  I found a registry patches for
correct the forcing election by WIN XP.  The laptop which provocate the crach
have not been modify by the patches and of course have provocated the panic action.

The 07/06/2004, all client cannot connect to server.  It's not possible, the
server must restart a nmbd !!!

The XP client is a laptop with latest security paches and it's on a IBM X40 laptop.

I am using Samba 3.0.7 and have similar problem (but w/o the daemon to crash). 
From time to time the domain master which is normally our PDC gets replaced 
with another machine, even that the 'os level = 65'. This is bad.
Comment 4 spurnelle 2004-09-22 08:03:11 UTC
You can by pass this problem with this modification : 
modify your smb.conf for set os level = 128

And if not work, you must modify each XP station with the registry editor:

Modify the parameter MaintainServerList which can find here:
HKEY_LOCAL_MACHINE \system\currentControlSet\Services\Browser\Parameters

The value can be : Yes, No ou Auto : Yes for others DC et other server, Auto for
master browser, No for workstations

please retest against 3.0.11 and reopen if you still see an nmbd crash.

sorry for the same, cleaning up the database to prevent unecessary reopens of bugs.
