I’m working in a school district which has a single domain (31 DC's in 28 sites). Every DC directs towards itself for a primary DNS, then to the 4 DCs at our primary technical site as the secondary, tertiary DNS and so on, and the sequence of the DC's is always the same. We also have an administrative complex and our alternative schools coursed to the 4DCs located at the prime site for primary DNS, secondary DNS, and so on.
Last summer, we virtualized four of our school servers and the DNS traffic from those buildings now course through the 4 DC's at our primary site. Later, we will discard our school servers to have every PC directing to the same DC for a primary DNS. However, I think that this might create too much traffic for just one server. Is it okay then to separate the different schools into four groups with each coursed to a different DC as primary DNS instead? Please note that this is an AD-integrated DNS using root hints.
How to course different groups to different DC as primary DNS?
I have read your question and I think I have a solution for you.
What you are trying to do is very good and you can do that very easily. You can either keep four of schools connected or can separate them. In case of traffic I suggest you to update your root hints in the DNS server. You can do that by following these steps:
Click Start, click Run, type dnsmgmt.msc, and then press ENTER. The DNS Manager console will open.
In the console tree, click the name of the DNS server you wish to configure.
On the Action menu, click Properties.
Click the Root Hints tab.
Modify server root hints as follows:
To add a root server to the list, click Add, and then specify the name and IP address of the server to be added to the list.
To modify a root server in the list, click Edit, and then specify the name and IP address of the server to be modified in the list.
To remove a root server from the list, select it in the list, and then click Remove.
To copy root hints from a DNS server, click Copy from server, and then specify the IP address of the DNS server from which you want to copy a list of root servers to use in resolving queries. These root hints will not overwrite any existing root hints
I hope that I could help you.
