[Samba] wins hook handling only own names

[Bgs]

  Hi all,

It might be an easy problem, but I haven't found anything in the docs...

I have a Samba3 PDC. I have wins hook set to a DNS update script. The 
script works fine, I tested it. My problem is that according to the 
scripts logging, samba only calls it for its own refresh.

It only sends lines like this every 20 minutes:

refresh SAMBA 20 259200 192.168.1.253

No client updates reach the script.

What could be the problem?

Thanks
Bgs
