We have a Samba 4 AD DC installation wich is also the DNS in our network.
It collects entries of all DHCP client machines with their addresses automatically. I can remember to have activated this behavior some day in the past, but can't remember where this had been. Of course I assumed it will drop old entries and not just collect new ones.
The screenshot explains it way better: DNS Manager Screenshot
Any idea where this setting can be? Thanks for any input!
