Comment 31 for bug 316862

2 upgrades amd64 lucid
1 fresh install x86 lucid
1 fresh install amd64 lucid
1 8.04 server
1 xp mce
2 xp home

without wins - same old intermittent nautilus / networking
(xp reports master browser issues interestingly enough)

will try to attempt this from

http://www.samba.org/samba/docs/man/Samba-HOWTO-Collection/NetworkBrowsing.html#browse-force-master

Forcing Samba to Be the Master

Who becomes the master browser is determined by an election process using broadcasts. Each election packet contains a number of parameters that determine what precedence (bias) a host should have in the election. By default Samba uses a low precedence and thus loses elections to just about every Windows network server or client.

If you want Samba to win elections, set the os level global option in smb.conf to a higher number. It defaults to 20. Using 34 would make it win all elections over every other system (except other Samba systems).
 ---------------------------------------------------------
will try making the ubuntu machines all 34 to see what happens
(maybe ubuntu needs to win the elections to fix the mixed os issue)

(works good with a wins server still)
