New Child Domain – Server Core and PowerShell

All of my domain controllers are now server core unless someone can give me a very good reason to install Windows with a GUI, so far no one has given me a good enough reason.

When deploying a new child domain this means we can now use some PowerShell goodness to create our new child domain.


Windows 2012R2 Server Core installed

IP address set on the box and preferred DNS server set to the IP address of a domain controller in the parent domain

Install-Windowsfeature AD-Domain-Services

Install-ADDSDomain -DomainType child -NewDomainName ‘childdomname’ -ParentDomainName ‘’ -InstallDns -CreateDnsDelegation -NewDomainNetBiosName ‘childdomname’ -DomainMode win2012r2 -Credential (get-credential)


You will be prompted for the admin credentials of your parent domain and then for the safemodepassword that you want to set on this DC.
