What are ForestDnsZones and DomainDnsZones?

When you install DNS server role, the DNS server service will attempt to create DNS application directory partition in Active Directory.

ForestDnsZones

DNS application directory partition for the entire forest. It contains all the DNS servers running on the domain controllers in the forest. DNS zones stored in this application directory partition are replicated to all DNS servers running on domain controllers in the forest.

DomainDnsZones

DNS application directory partition for each domain in the forest. DNS zones stored in this application directory partition are replicated to all DNS servers running on domain controllers in the domain.

In case these partitions are not created then it can be created manually using dnscmd commandline utility.
Remember  you need to be member of Enterprise Admin group in order for you to successfully create application directory partition.

These partitions are available only if you have AD intergrated DNS. You must also remember that this partitions are not replcated over to GC.
