Prepare Active Directory with powershell

Prepare Active Directory Domain Service with 2012 R2 Powershell Script

If you're planning to Install Active directory on multiple DCs for backup, you can speed up this process by using the following script which is provided by Microsoft. but you'll have to copy and paste it in notepad and save it in .ps1 extension after editing the Domain Name and Domain Netbios name.

You may also wanna change the forest mode to match the one in your environment if you already have an old DC. 

# Windows PowerShell script for AD DS Deployment 
# 
Import-Module ADDSDeployment
Install-ADDSForest `
-CreateDnsDelegation:$false `
-DatabasePath "C:\Windows\NTDS" `
-DomainMode "Win2012" `
-DomainName "moh10ly.com" `
-DomainNetbiosName "Moh10ly" `
-ForestMode "Win2012" `
-InstallDns:$true `
-LogPath "C:\Windows\NTDS" `
-NoRebootOnCompletion:$false `
-SysvolPath "C:\Windows\SYSVOL" `
-Force:$true
Note: If you want to have a different Computer name, you will need to change that manually before you start the process below and restart after changing the computer name. 
You will need to install the AD Domain Service management tools before you are able to run the powershell 

Install-windowsfeature -name AD-Domain-Services –IncludeManagementTools
