Creating a new Active Directory for a test environment is something I seem to have to do multiple times a week. I hope to never have to do it the long way with the GUI again.
The following PowerShell commands installed AD DS and creates a new forest/domain called “domain.co.uk”. You are prompted for the AD Restore Password, the rest is automated.
Install-AddsForest -DomainName domain.co.uk -CreateDnsDelegation:$false -DatabasePath "C:\Windows\NTDS" -DomainMode "Win2012R2" -DomainNetbiosName "DOMAIN" -ForestMode "Win2012R2" -InstallDns:$true -LogPath "C:\Windows\NTDS" -NoRebootOnCompletion:$false -SysvolPath "C:\Windows\SYSVOL" -Force:$true
