Environment is Server 2012 R2. Our DNS allows both secure and non-secure registration of devices in DNS.
When I asked about that, I was told printers, phones were among some of the devices that would get an IP from DHCP that might need to register in DNS. I wasn't so sure. I would think that if DHCP issues an address, that address could register in DNS, but after some reading, I see secure means domain joined. So, workgroup computers could not register, and that's fine, but printers? Phones?
I need some clarity on secure vs nonsecure where DNS updates is concerned. To my memory, I have never set up anything but secure and never had a problem.
