[Samba] WINS server looses election irregular in a heterogeneous network

[Timo Meinen]

Dear Charlie,

thank you for the tip of setting "announce version" to keep Master Browser.
But it just keeps Master Browser for 6 hours. This is the nmb-log:

===

[2008/06/19 23:51:00, 2] nmbd/nmbd_elections.c:run_elections(204)
  run_elections: >>> Won election for workgroup WODANLAN on subnet 10.0.80.5<<<
[2008/06/19 23:51:00, 2]
nmbd/nmbd_become_lmb.c:become_local_master_browser(525)
  become_local_master_browser: Awaiting potential browser state. Current
state is 4
[2008/06/19 23:51:09, 0]
nmbd/nmbd_incomingdgrams.c:process_local_master_announce(309)
  process_local_master_announce: Server ERSTER at IP 10.0.80.219 is
announcing itself as a local master browser for workgroup WODANLAN and we
think we are master. Forcing election.
[2008/06/19 23:51:09, 2]
nmbd/nmbd_become_lmb.c:unbecome_local_master_browser(280)
  unbecome_local_master_browser: unbecoming local master for workgroup
WODANLAN on subnet 10.0.80.5
[2008/06/19 23:51:09, 0]
nmbd/nmbd_become_lmb.c:unbecome_local_master_success(149)
  *****

  Samba name server SHODAN has stopped being a local master browser for
workgroup WODANLAN on subnet 10.0.80.5

  *****
[2008/06/19 23:51:11, 2] nmbd/nmbd_elections.c:send_election_dgram(41)
  send_election_dgram: Sending election packet for workgroup WODANLAN on
subnet 10.0.80.5

Do you have any other ideas? I don't understand why the election is won when
the server is restarted, but why it is lost, when it keeps a few hours
online.

Best regards,

Timo
