Hi,


Did you mean some of the clients point to one DC1 as the Primary DNS Server while some clients point to another DC as the Primary DNS Server?

Actually, In a larger environment, at least two domain controllers at each physical site should be DNS servers.
This provides redundancy in the event that one DC goes offline unexpectedly. Note that domain-joined machines must be configured to use multiple DNS servers in order to take advantage of this.
Based on my understanding , it would be ok to do this.
