[Samba] Samba 3.5 loses local master browser election to Win7 32bits

[Gaiseric Vandal]

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?
