Hi Expert,

What could be the best practice for member's AD DNS setting?

Normally at Primary AD, the preferred DNS setting is point to it own IP, secondary IP is point to backup AD or member AD,

should we add in all member's AD IP address's into primary AD's DNS setting?

for member AD, preferred DNS is point to primary AD's ip address?

For my case, i'm having 4 Active Directory

please advise

Thanks
Alfred

- As multiple DCs are configured as DNS servers, they should be configured to use each other for resolution first and themselves second.

- Each DC's list of DNS servers should include its own address, but not as the first server in the list.

- If a DC uses only itself for resolution, it may stop replicating with other DCs. This is obviously not an issue in a domain with only one DC.
