Samba constantly loosing elections. Weirdness in browsing..

I have a network with 2 samba servers, 16 NT-wks (sp3), and some 70 Pc's
running windows95. I experience weirdness in browsing..

The first Samba is a 2.1.0prealpha (pdc, wins, homes, NIS auth server
and such). (smb.conf further down)

The second server (apps and such) is a NIS-client, and runs
security=server. (samba 2.0.0beta5) (smb.conf further down)

I have several problems here, (slowness in logging on to a NT-wks,
cannot find app-server in 'Network Neighborhood'...and so on..) 
and I think all the problems are connected to this one:

I am running WINS on the samba-pdc, and when i list resources on the
server, it always thinks it is master of the domain. However, if I list
the apps-server, it usually thinks one of the nt-workstations is the
master. If I apply a registry patch to Nt-wks's, they stop
appering in PDC's browse list. (patch lower down, nomaster.reg)

The next thing that happened is that a windows95 machine that had
file-sharing installed wanted to be master. Eventhough I have os level on
64 on the pdc, it never gets to be the master browser :( 

I took away file-sharing on the windows95 machine, and now the pdc-server
doesn't see *any* other machine in the browse list. Looks like you have to
have at least one windows machine that fights elections in order to get
the election process going, but why isn't samba always winning?

Ok, I re-installed the browser on some NT-workstations, and now I can see
every Nt-workstation and the Samba app-server, both in Network
Neighborhood on the NT-wks's and in the pdc's browse list. But, browsing
the app-server still reports a nt-workstation as master browser. I have
disabled netbios interface on Nt-workstations, and they are only running

Sometimes the pdc *is* master, but when it isn't, logging on to a NT-wks
takes about 1 minute. When I have samba-pdc as master browser, logging on
usually takes less than 10 s.

Isn't there any other way to let the pdc win elections more securely?
Or is there something I've missed in configuring the network?

Here is some output from log.nmb:  

[1999/01/10 20:05:39, 0] nmbd/nmbd.c:sig_hup(93) 
  Got SIGHUP dumping debug info.  
[1999/01/10 20:05:39, 0] nmbd/nmbd_workgroupdb.c:dump_workgroups(308) 
   dump workgroup on subnet netmask=

   dump workgroup on subnet UNICAST_SUBNET: netmask= 
        SAMBA(1) current master browser = UNKNOWN


What is UNICAST_SUBNET? And why does samba-logs say that it is:

[1999/01/10 18:42:38, 0] nmbd/nmbd_logonnames.c:become_logon_server_success(118) 
  become_logon_server_success: Samba is now a logon server for workgroup
	SAMBA on subnet

On subnet Shoulnd't this be something like ?

=================== relevant parts of smb.conf from PDC-server:  ;  ;

Relevant parts of apps-server's smb.conf:
