[Samba] WINS, must be master browser?

[Tim Smith]

i have an NT4 server and a linux samba server. the NT4 server is 
currently the WINS server. it works perfectly. i want to ditch it and 
use my samba server as the WINS server, however WINS simply does not 
work. could this be becuase the WINS server also needs to be the local 
master browser?

here is the global section of my smb.conf
[global]
        workgroup = laboratory
        os level = 2
        kernel oplocks = No
        security = user
        encrypt passwords = Yes
        guest account = Nobody
        map to guest = Bad User

in this config samba will not win browser elections. I know the NT4 
machine will win all browser elections, it's the only difference i can 
think of.
