Attached (assuming this list still allows attachments :)

No.

Yes.  Of course you can put them in via nsupdate manually, which is what I do.

wins hook = /usr/local/samba/bin/dns_update

"nsupdate" is the BIND async client,  Samba cannot call this directly.  The
aforementioned script is a wrapper around nsupdate.  You could of course update
your named files some other way, but why....

Unfortunately documentation of "nsupdate" is ****scarce****.  My
little-green-men probing techniques turned up this:

1. Input to nsupdate MUST end in a blank line or NOTHING will happen.
2. Input to nsupdate looks something like this:

update delete toshiba.morrison.iserv.net. 
update add toshiba.morrison.iserv.net. 3600 A 192.168.1.254 

See the periods on the ends of the names? You need those.

And a reverse update looks something like:

update add 105.1.168.192.in-addr.arpa 8600 IN PTR eds01423.morrison.iserv.net.

Ugly? Yes.  See the period on the end of the name?

And guess what,  failure of nsupdate doesn't seem (by default) to produce an
error message in any log file anywhere.  Makes getting it working BIG fun!

And don't forget to grant the host that is you WINS server the ability to
perform async updates on the BIND host.
