PowerShell ADDS-Domain-Controller Feature Name Not Valid

May 13, 2014

This error appeared after running a PowerShell script on Windows Server 2012 R2:

The role, role service, or feature name is not valid: “ADDS-Domain-Controller”. The name was not found.

This script had been working on Windows Server 2008 R2. Running Get-WindowsFeature on Windows Server 2008 R2 shows these available features, including ADDS-Domain-Controller:

Features in Server 2008 R2

However run the same command on Server 2012 R2:

Features in Server 2012 R2

Notice ADDS-Domain-Controller is no longer present. Instead, install the feature AD-Domain-Services, which will take care of part of the task. dcpromo is now also depricated for Windows Server 2012. Replace that command with Install-ADDSForest or Install-ADDSDomainController. I’m installing a brand new domain so I’ll use the forest cmdlet:

Install-ADDSForest –DomainName $domain –DomainMode Win2012 –ForestMode Win2012 -Force -SafeModeAdministratorPassword (convertto-securestring $password -asplaintext -force) –DatabasePath $locationNTDS –SYSVOLPath $locationSYSVOL –LogPath $locationNTDSLogs -verbose

Summary: Replace ADDS-Domain-Controller and dcpromo with AD-Domain-Services and Install-ADDSForest
