Creating a new AD forest
One big change with Windows Server 8 is that dcpromo is no more – its gone, gone gone.
Instead the promotion wizard is started from Server Manager. Install the AD Domain Services role and you will see a notification at the top right of the Server Manager console with a complete Active Directory configuration option. Click that and the wizard starts. If you’ve used dcpromo on earlier versions of Windows there won’t be any surprises.
Best of all you get the PowerShell commands to do the job
-DatabasePath "C:\Windows\NTDS" `
-DomainMode "Win8" `
-DomainName "Beta8.test" `
-DomainNetBIOSName "BETA8" `
-ForestMode "Win8" `
-LogPath "C:\Windows\NTDS" `
-SYSVOLPath "C:\Windows\SYSVOL" `
already to be re-used. The AD Administrative Centre also produces the PowerShell it uses under the hood but thats a story for another day.
The ADDSDeployment module has a number of cmdlets
PS> Get-Command -Module ADDSDeployment
I’ll be trying out the Install-ADDSDomainController soon
