How-To : Promote Windows Server 2012 Core to first Domain Controller in Forest

by | Aug 7, 2013 | Directory Services, Infrastructure, Scripting, Windows | 3 comments

In order to create new Forest and promote Windows Server 2012 Core to be Domain Controller for that Forest, first Active Directory Services Role has to be added:

Install-WindowsFeature AD-Domain-Services –IncludeManagementTools

Once Active Directory DOmain Services role is installed we can promote server to be first Domain Controller in the Forest.

Install-ADDSForest -DomainName "lab.corp" -DomainNetbiosName "LAB" -DomainMode Win2008R2 -ForestMode Win2008R2 -InstallDns -Force

And after some time new Forest and Domain Controller is ready to use.

    In Windows Server 2012 R2 PowerShell will give an error for the Install-ADDSForest cmdlet if you don’t specify the -SafeModeAdministratorPassword parameter.

    ——————–

    Install-WindowsFeature AD-Domain-Services –IncludeManagementTools

    ——————–

    ——————–

    Import-Module ADDSDeployment

    $SecurePassword = “P@ssw0rd” | ConvertTo-SecureString -AsPlainText -Force

    Install-ADDSForest -DomainName ‘Doge.com’ -SafeModeAdministratorPassword $SecurePassword -DomainNetbiosName ‘DOGE’ -DomainMode Win2012R2 -ForestMode Win2012R2 -InstallDns

    Thanks Joseph. Your procedure works for me with Windows 2012r2 Core.
