Maybe I've got things wrong, but what entity is responsible for updating
the A records in the Samba DNS servers, and when? Just an example, I
have got a Windows 10 workstation with the following data in the AD DNS
Type: Host (A)
Timestamp: 4/7/2019 11:00:00 AM
The workstation is used every day, restarted frequently, having the
latest Windows updates, but the IP address for the A record is wrong,
currently it is 172.16.10.185 (from the DHCP server). Shouldn't the
Windows 10 workstation register itself with the AD DNS with the given IP
address? The tick box is checked for the IPv4 settings.
If my questions seem stupid or based on lack of knowledge, please
correct me, so I can learn from this and get things right.
