Because the zones are Active Directory integrated? All domain controllers can write to their own copy of the DNS zone, they are all primary so to say. If one domain controller fails, the registration continues on the one which you configured as second dns server in your network card configuration.

- thanhtien19Feb 09, 2022Iron ContributorYes , here I worry member server set primary dns is AD1 , secondary AD2 . IF AD1 offline can effect to resolve dns of member ?
- Feb 09, 2022If the member server can't reacht AD1 for DNS resolving, and it has AD2 configured as secondary dns... Then it will use AD2 for DNS resolving, it the DNS zone is AD Integrated then AD2 will always have a synced up-to-date writeable copy of the DNS zone.
If you're worried about this, remove the AD1 DNS ip-address from the member server so that it only has AD2 as it's DNS server. If everything still works, then you know enough 😉
