When you install Acrive Directory Domain Services (AD DS) on Windows Server 2012 domain controllers by using the Windows PowerShell AddsDeployment module, you receive the following message:
Then, this messages is displayed again.
You first receive this message because of the domain controller deployment prerequisite validation process that was added in Windows Server 2012. Then, you receive this message again during the actual installation.
When you install AD DS by using Windows Server 2012 Server Manager, you receive this message together with dialog boxes that make the message more understandable.
To resolve this issue, ignore the message.
If you use the -SkipPreChecks:$true argument, you receive the message only one time. However, we do not recomment that you use this argument, because the prerequisite checks prevent you from trying a domain controller installation that will fail.
Both messages are expected when you create a new AD DS forest. For more information about the DNS delegation warning, go to the following Microsoft TechNet website:
