there are (at least) 2 ways to manipulate samba (windows) dns entries:
  - using dce/rpc calls to modify the AD directory directly
    (e.g. used by samba-tool, MS DNS Manager GUI, ...)
  - using dynamic DNS
    (e.g. ISC nsupdate, MS ipconfig /registerdns, ...)

When samba starts, the internal dns server reads all currently defined
zones (from ADS) - and the containing dns records - into its _own_ data structures.

When a new zone is added, the dce/rpc tools will show it,
but the internal dns must be restarted.

When you then add new records to any now existing zone, the dns server
will also track them. So no samba restart is needed.

Cheers, Günter
