Since upgrading our samba servers on all our Unix machines
(Solaris 2.5.1 and 2.6 an Sun Servers) to versions 1.9.17p2 and p4
we observe the "Hosts disappearing from browser list" problem.
In patch level 2 (1.9.17p2) an error was logged in the log.nmb file,
"WINS server did not respond to name registration!"
When samba is first started the Hosts are browseable on 95 and NT,
but after a period of time they dissapear from our WINS server.
If nmbd is restarted they temporarily reappear.
The setup is as follows,
>workgroup = SANDWICH-CR
>domain controller = san-dom-02
>os level = 0
>preferred master = no
>wins support = no
>wins proxy = yes
>wins server = san-dom-07
>local master = no
>server string = CR Sandwich Workstation (%h) (Samba %v)
>username map = /etc/samba/username.map
>password server = san-dom-02
>password level = 2
>security = server
>default service = homes
>netbios name = maxwell
>browseable = yes

I tried 1.9.17p0 and it was okay, so the break was moving to p2. The
negative response fix in p4 removes the "WINS server not respond..."
warning message, but we still have non-browseable servers.
Can anyone help ???
