DNS order in Active Directory Server
If they're all in the same site it really doesn't matter.
Dave PatrickIf change FSMO to another server then need change dns client point to this server hold FSMO ? and what's happen if DC1 failure then all server point dns first to DC1 has problem ?
If change FSMO to another server then need change dns client point to this server hold FSMO ?
No, this is not necessary. Intrasite DNS replication occurs within 15 seconds, 15 minutes max.
and what's happen if DC1 failure then all server point dns first to DC1 has problem ?If the FSMO role holder fails then you can seize roles to another healthy one
Transfer or seize FSMO roles - Windows Server | Microsoft Docs
then perform cleanup

then rebuild the failed one.
- I still worry about DNS Client in active directory . Link two way https://docs.microsoft.com/en-us/troubleshoot/windows-server/networking/best-practices-for-dns-client-settings
Method 1 : prefer DNS 127.0.0.1 alter all dns remain
Method 2 : prefer DNS primary dc fsmo alter all dns remain and last 127.0.0.1
So best howNot sure what the worry is. Whether a domain controller holds FSMO roles or not has no effect on DNS services.
