We are using Windows 2008R2 servers.
In DHCP what is the best practice for the DNS setting under the DNS tab under scope properties.
I see a tab to enable DNS dynamic updates according to the setting below. Under this setting I see two options.
Option one: Dynamically update DNS A and PTR records only if requested by client.
Option two: always update DNS A and PTR records.
Also have options to Discard A and PTR records when release is deleted or to Dynamically update DNS A and PTR records for DHCP client that do not request updates.
Need to know what the best practice for this is on a large network? I have several subnet with their on DHCP and DNS servers.
