By default, Windows DHCP is configured to dynamically update PTR records on behalf of client computers.
Clients capable of dynamically updating their own records attempt to update DNS on their own. You can change this default behavior so that the DHCP server updates both the host records and the PTR records on behalf of clients. The following table shows Windows DHCP settings for controlling Dynamic DNS updates and their Address Manager equivalents.
|DHCP Setting in Windows||Address Manager Service Deployment Option|
|DDNS—Enable DNS dynamic updates||DDNS Updates—enabled|
|DDNS—Disable DNS dynamic updates||DDNS Updates—disabled|
|DDNS—Dynamically update DNS A and PTR records only if requested by the DHCP Clients||Client Updates—enabled|
|DDNS—Always dynamically update DNS A and PTR records||Client Updates—disabled|
