Samba election incompatibilites? (MS KB article Q168821)
I read the Microsoft knowledge base article at
http://support.microsoft.com/support/kb/articles/Q168/8/21.ASP ,
which claims that Samba's method of conducting browser elections is
"incompatible" with Windows. There was some discussion of this on
this list, with one message
(http://samba.cadcamlab.org/lists/samba/Mar2000/00138.html)
apparently acknowledge a flaw in samba. However, I can't find any
indication of whether it has been addressed.
I ask because I am running Samba 2.0.7 (from the Debian GNU/Linux
2.2 package, without much customization), and recently came to work
to find that my computer had been unplugged from the network,
because it had refused to give up "master browser" status (having
obtained it during a reboot of an NT machine). The global part of
my configuration is appended, but most relevant settings are at
their defaults. I believe the Windows side of our network is a
pretty standard NT 4.0-based installation.
I was very surprised to find that the samba defaults could create
this (rather serious--apparently, browsing was completely broken on
many windows clients) problem. Can someone give me more
information?
Email Cc: appreciated.
Thanks,
Andrew

The global part of[snip]> os level = 20I believe the above line is the problem. When the NT machine went down, the Windows systems held an "election", and the Samba server won it (it stacked the deck in its favor with that os level). I'd suggest you change the os level to 0, restart Samba, then see if it gets elected when the NT system goes down. Calvin -- Calvin Dodge Certified Linux Bigot (tm) http://www.caldodge.fpcc.net
