Hi,
Always dynamically update DNS A and PTR records" - Which mean we are asking DHCP to register DNS records on behalf of client machines. If you run DHCP on DC, DHCP will not register records in DNS unless we set credentials (standard user credentials). You can create one user and use his credentials for DNS registration, you don't need to use Admin accounts.credential tab will be found under IPv4 properties\Advanced tab
Instead of above option you can use another option "Dynamically update A and PTR records only if requested by DHCP client machines". If we select this option, client will register A records and DHCP will register PTR records. We need to set credentials for registering PTR records.
Discard A and PTR records when lease is deleted
Please understand that discard does not mean delete records by DHCP server itself immediately, system will clean these records only if DNS aging/scavenging settings on DNS server is set properly.
You should create a dedicated user account and configure the DHCP servers with its credentials under the following circumstances:
•The DHCP server is configured to perform DNS dynamic updates on behalf of DHCP clients.
• A domain controller is configured to function as a DHCP server. Without the dedicated user account, secure updates will not work.
• The DNS zones to be updated by the DHCP server are configured to allow only secure dynamic updates.
More information about DNS dynamically update , please refer to the following article:

Hi,
Since Win 2003 running DHCP on a DC has been supported, DHCP whit DC is good choice to easily manage secure dynamic update and Active Directory-integrated DNS. The best option is "Always dynamically update DNS A and PTR records "
When DHCP separate of DC, two options all available.
