CNS Network Register and Active Directory

The CNS Documentation suggested that

" Do not create a Windows domain that equates to a DNS zone (such as Instead, create a subdomain, such as " in the following page

However in

on page 2, the suggestion was "If the domain should be the same as the Zone, contact Cisco Technical Help Center for Assistance"

I have a domain and an Active Directory on a root domain controller with domain name The DNS and DHCP servers run on Cisco CNS Network Register.

Is there a real technical reason why I can not use AD Domain and domain controller and zone

Should I consider this an invitation to simply migrate to Microsoft DNS and DHCP infrastrcuture even though my network gears are almost all Cisco?
