DNS order in Active Directory Server
We have 6 server active directory
- 3 server in DC : DC1,DC2,DC3
- 3 server in DR : DR1,DR2,DR3
- ALL server the same site in active directory (Default first Site)
- DC1 : hold FSMO (5 role)
DNS client order of active directory as below
DC1
Primary : DC2
Second : DC3,DR1,DR2,DR3,127.0.0.1
DC2
Primary : DC1
Second : DC3,DR1,DR2,DR3,127.0.0.1
DC3
Primary : DC1
Second : DC2,DR1,DR2,DR3,127.0.0.1
DR1

Tien Ngo ThanhSo should all dc point to Primary : DC1 ? because it hold FSMO .
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 ?
