I agree that preferred master should have been set to yes.  I made that
change with but still no joy.

I don't mean to be contrary but our cross subnet browsing has been working
since 2003 when we set up this network.  It has been very reliable and I
depend on it to work.  And I believe it is because of have our WINS servers
the way that they are.

I do think that I have hit upon an issue.  The WINS data for samba is kept
in /var/cache/samba.dat but it is updated dynamically with nmdb.  It has
dated data.  When I moved the server I changed the server name slightly and
so the WINS data points to the old name at the current IP.  In fact with
this network rebuild I changed most of my computer names and they are all
incorrect.  I think I need to shut down all three instances of samba clear
the wins data and then start them all again so that they populate from
