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

[Chris Rowson]

I'm currently testing samba 4, and I've come across a problem which I can't
seem to find an answer for.

I have one samba 4 ADDC running on a Centos 6 container, compiled from the
latest stable source release and setup as per the samba wiki. I'm running
the internal DNS server.

DHCP is provided to the network by an openwrt router. The router is
configured to hand out the DNS server details of the ADDC.

I have joined a windows 8 virtual machine to the domain, it gets an IP
address from the router, but internal DNS running on the ADDC doesn't seem
to add an A record for my windows client.

I've tried running ipconfig /registerdns on the win client but get an
unable to update DNS error.

I'm sure I'm missing something here. Can anybody help?

Thanks in advance,

Chris
