I am working in Microsoft Windows Server 2012.  I have made a Domain Controller for my first Forest, "mysite.com", using the "ADDS Configuration Wizard"

Now I want to create a new Domain in mysite.com as domain1.mysite.com using the same Wizard using the second option.

I run thru (see bottom for PS) and I make it all the way to "Prerequistes Check"  and I get this error:

"Verification of prerequisites for Domain Controller promotion failed. The specified argument 'ChildName' was not recognized."

Here is my PS code:

#
# Windows PowerShell script for AD DS Deployment
#

Import-Module ADDSDeployment
Install-ADDSDomain `
-NoGlobalCatalog:$false `
-CreateDnsDelegation:$true `
-DatabasePath "C:\Windows\NTDS" `
-DomainMode "Win2012" `
-DomainType "ChildDomain" `
-InstallDns:$true `
-LogPath "C:\Windows\NTDS" `
-NewDomainName "domain1" `
-NewDomainNetbiosName "DOMAIN1" `
-ParentDomainName "mysite.com" `
-NoRebootOnCompletion:$false `
-SiteName "Default-First-Site-Name" `
-SysvolPath "C:\Windows\SYSVOL" `
-Force:$true

What is you try using child instead?

You can simply use the UI and then click on View Script to get the script.

I did make a copy using "View Script", it is the PS you see above.

I need a resolution of this error:

"Verification of prerequisites for Domain Controller promotion failed. The specified argument 'ChildName' was not recognized."

OK. Could you please try removing the "" and try again?

Hi,

Any update about the issue?

Regards.
