I’d like to know what is the best way to assign Primary and Secondary DNS server in a large enterprise?
Where the majority of the servers are located in Data Centre AD site and all of the workstations are in Head Office AD site. The AD topology is just single AD domain forest.
Data Center building (AD Site: Data_Center) ~ 350 Windows servers:
PRODDC01-VM (AD Domain Controller, DNS Server)
PRODDC03-VM (AD Domain Controller, DNS Server)
Head Quarter building (AD Site: HQ) ~ 250 Windows workstations:
HQDC01 (AD Domain Controller, DNS Server, DHCP Server)
Note: There are some more DC/DNS server in both sites above but they are to be decommissioned due to old Win2003 box.
So what is the best recommended configuration for the Server DNS setting and the work station DNS settings based on three AD integrated DNS above on both AD sites ?
