[Samba] Samba 4 ADDC. Dynamic DNS updates from Windows clients.

[Chris Rowson]

So I gave 'Domain Computers' group the READ and CREATE ALL CHILD OBJECTS
permission on the forward lookup zone.

Doing an ipconfig /renew on Windows 8 does not create an A record. Doing an
ipconfig /registerdns does however create a new record. Hooray. I wonder if
I just need to turn on dynamic updates in Group Policy to force this
behaviour at interface renew/boot etc? Will experiment later after sorting
out the various other problems!

I then attempted to change the IP Address on the Win 8 client and re-ran
ipconfig /registerdns. This time it did not update the DNS A record.

The Windows Event logs shows

EventID 8016
The system failed to register host resource records for network adapter
with settings...

The reason the system could not register these RRs was because the DNS
server failed the update request. The most likely cause of this is that the
authoritative DNS server required to process this update request has a lock
in place on the zone, probably because a zone transfer is in progress.

I'm going to have to stop hammering away at this problem for a while
because I've had enough! Hopefully somebody here will be able to give me
some inspiring advice. :-)

Should setting up dynamic DNS updates for Windows clients be this hard?
Have I done something completely wrong?

Cheers,

Chris
