Did you ever deploy this solution? One issue I see for using DNS Express for Windows DNS is Dynamic DNS registration.

 

Referencing this technet article. https://technet.microsoft.com/en-us/library/dd197552(v=ws.10).aspx

 

"The client processes the SOA query response for its name to determine the IP address of the DNS server authorized as the primary server for accepting its name. It then proceeds to perform the following sequence of steps as needed to contact and dynamically update its primary server."

 

We compared the SOA response from a Windows AD integrated DNS server and the GTM with DNSExpress configured as a Secondary.

 

The GTM will only respond with an SOA record of the DNSExpress hidden master for the zone file. This appears to be a single point of failure for dynamic DNS registration.

 

What affect would this have if you have a large network that spans multiple countries? Maybe not an issue, but just a thought.

 

If anyone has deployed this successfully, it would be nice to know their experiences.
