samba - Jan 2002 - DHCP and WINS.... wins.dat is out of date

My wins.dat seems to be rather out of date.  I'm running Samba 2.2.2 as a
wins server with dhcp.  When the client address changes, Samba doesn't seem
to update wins.  The clients are Win2k & WinXP.  In the manual page, it
suggests that I shouldn't change the max/min ttl parameters.  Can I hook
dhcp to samba somehow?

Rebooting the out of date clients triggered Samba to update wins.dat right away.
Perhaps this is more of an issue with windoz not telling Samba that it's ip
changed.  I don't want to rely on m$ though... that's usually a bad
idea.

I'm looking for a good way to synchronize DNS, DHCP, and WINS.  Currently, I
have a script that runs every 15 minutes to try to compile DNS files based on
browse.dat and results from nmblookup.  I used to use wins.dat, but it's
never as current as browse.dat (why doesn't Samba update them together???).

Anyone else running Samba with dhcp?

The way I do this with my networks is as follows:

ISC DHCP 3.0

ISC BIND 8 or 9

Samba (2.2 will do)

Setup the dhcpd.conf to give out the wins server's address:
    option netbios-name-servers 192.168.2.99, 192.168.2.99;
(yes twice, it helps when the server is down, client retries for twice
as long)

Also setup dynamic dns (see dhcpd.conf manpage).

Setup Samba as a wins server, but also set 'dns proxy = yes'.   This
will mean that any host in DNS (now kept sane by dynamic DNS) will also
appear as a WINS host.

I don't attempt to update DNS from wins becouse I find the DHCP way
sufficient, all windows clients supply their machinename as requested
and it 'just works'.
