Move bulk computer objects listed in TXT file to specific OU in Active Directory

• List down the servers you want to move in a file named "server.txt".
• Then find the correct OU where you want to move all computer objects.
• Note: We assume we need to move the computer accounts in Servers OU under the nilabh.com domain.
• Run the following script to move all computer objects listed in the notepad file to the required OU.

$Servers = Get-Content "C:\servers.txt"

$TargetOU = "OU=Servers,DC=nilabh,DC=com"

ForEach( $Computer in $Servers ) {

Get-ADComputer $Computer | Move-ADObject -TargetPath $TargetOU

}
