Hello,
I have DHCP server running on Domain Controller. OS is Windows Server 2003 R2 Standard SP1.
DHCP server has options:
Enable DNS dynamic updates according to the settings below - Enabled
Always dynamically update DNS A and PTR records - Enabled
Discard A and PTR records when lease is deleted - Enabled
Dynamically update DNS A and PTR records for DHCP clients that do not request updates - Enabled
User account to update DNS records is not set on DHCP advanced settings.
AD integrated DNS zone allows only secured updates.
I know this configuration this against MS best practice. I have created a new user account for this purpose.
My question is, what happens to existing DNS records when I configure this user account to DHCP server? Is there any adverse effects if I make this change? If I take a look at some DNS A record, I see that the Owner of that record is SYSTEM. I suppose this is because DHCP server exists on Domain Controller instead dedicated server.
