I work for a large scale company and we are cleaning up our DNS in addition to implementing new Windows Server 2008 R2 systems. We have multiple domains that have been created throughout the years. I have noticed a sub-domain that is giving us an error with the DNS Best Practice Analyzer. It appears they originally clicked on the zone and selected "New Domain" instead of just creating a separate zone. I have not seen this method used before. I have been searching for the Microsoft Best Practice method to prove of disprove this configuration should be changed to it's own new zone. Can anyone help me answer this?
Your help is greatly appreciated.
