Ensure that you create the necessary reverse zones for all of the subnets used in your environment, using the DNS/DHCP Management Console.The designated primary for a zone (forward or reverse) that is under the DSf W domain must be the server that handles the dynamic updates.

Stub zones (and conditional forwarding for that matter) typically are for situations where you want to resolve DNS names that aren’t on the internet.

If you use to make the stub zone Active Directory integrated, the zone is stored in AD, and is replicated to at least all the domain controllers in the domain where you created the stub zone, and potentially through the forest.

The key difference between the two in the end as far as functionality is concerned is that stub zones have the distinct advantage of automatically updating what the DNS servers are for the other domain, so long as the administrators of the other domain keep the NS, SOA, and glue A records updated properly.

Many DNS administrators configure the DNS servers in a way that the zone transfers can take place only between the specified DNS servers.

By configuring the DNS servers this way, the administrators can reduce the security risks that may otherwise remain high when the DNS servers are configured to forward the DNS updates to all the DNS servers that request them.

The advantage of stub zones increases the more external domains your DNS servers must resolve other than through internet DNS servers, the more the external domain’s DNS servers change, and the more segregated the management of the DNS servers between the domains are.

For example, if domain1.local’s DNS zones are managed by a different team than domain2.local’s DNS servers, either domain’s admins might not remember to tell the admins of the other domains that DNS servers have changed. Yet, stub zones are consistently the redheaded stepchild in DNS design. They’re extremely useful, and we should look to use technologies that can help automate our environments. To get started, you need to find the DNS records for your domain in Windows-based DNS so you can update them. Get support.) Note: Typically it takes about 15 minutes for DNS changes to take effect.Also, if you're planning to synchronize your on-premises Active Directory with Office 365, make sure you don't need to first update your user principal name (UPN). However, it can take up to 72 hours for a changed record to propagate through the DNS system.With that said, between the two, stub zones are the better choice, provided your DNS environment meets the following: I think honestly people just know conditional forwarding works, they understand how it works, so they use it instead, even when stub zones would be the clearly better choice.I only point out that if name servers may change either by adding or removing them from the external domain, you have to keep on top of that, whereas stub zones would automatically update in those events. The first domain controller in the tree hosts the DNS server by default.
