Hello,

I'm having a problem with my [Samba4 DC - bind9 (DDNS)] configuration.
On my Windows XP clients, registration with the reverse zone works correctly.
However, on Windows 7 or later clients, there are no update requests for the reverse zone:
- There is a transaction for both zones from an XP client.
- For Windows 7 or 2008 R2, only one transaction is initiated.

Are you experiencing this issue?

Hello,

Problem solved.
It was indeed a client-side issue.
In the advanced TCP/IP settings of the Ethernet adapter, under the DNS tab, you need to check "Use the DNS suffix of this connection for DNS registration".
