I have a windows domain with a win server 2012 domain controller with dns service installed. In the DNS server there is the automatic DNS registration, is it possible to limit these registration only for domain machines? Now in my dns I can found anything... printers, mobile devices, and so on.
To avoid this problem perform the following 3 steps (It is important that you follow all the steps to avoid the issue). 1. Under Network Connections Properties: On the Unwanted NIC TCP/IP Properties -> Advanced -> DNS - > Uncheck "Register this connections Address in DNS" 2. Open the DNS server console: highlight the server on the left pane Action-> Properties and on the "Interfaces" tab select "listen on only the following IP addresses". Remove unwanted IP address from the list 3. On the Zone properties, select Name server tab. Along with FQDN of the DC, you will see the IP address associated with the DC. Remove unwanted IP address if it is listed. After performing this delete the existing unwanted Host A record of the DC.
It looks like you are also running DHCP Server service on a Windows Server. Go to DNS tab in the DHCP scope properties and clear "Dynamically update DNS A and PTR records for DHCP clients that do not request updates" checkbox.
