In looking at the AD partitions using ADSIEdit I see that both the Domain partition and the DomainDnsZones partitions have a DC=RootDNSServers container which both contain objects of dnsNode class representing the Root Hint servers. I have two questions about this:
Why are the Root Hints being stored in AD? I always understood that they were loaded from the "C:\Windows\System32\dns\cache.dns" file.
Why are they stored in both the Domain and the DomainDnsZones partitions?
