Script to Rename Computers in Active Directory

1. Run this PowerShell Script to rename 1 computer:

$admin = "KIMCONNECT\"+ Read-Host "Enter the admin username"
$pass = Read-Host 'Enter the admin password' -AsSecureString
$oldName = Read-Host 'Input Current Computer Name'
$newName = Read-Host 'Set $oldName As'

function renameComputer{
	param (
	    [Parameter(Mandatory)][ValidateNotNullOrEmpty()][string[]]$old,
	    [Parameter(Mandatory)][ValidateNotNullOrEmpty()][string[]]$new,
	    [Parameter(Mandatory)][ValidateNotNullOrEmpty()][string[]]$adminID,
	    [Parameter(Mandatory)][ValidateNotNullOrEmpty()][string[]]$password
	)

    Write-Host "Renaming computer from: $old to: $new using $adminID with $password`nPress Ctrl + C to abort";
    pause;
    netdom renamecomputer $old /newName:$new /uD:$adminID /passwordD:$password /force /reboot
}
renameComputer -old $oldName -new $newName -adminID $admin -password $pass

2. To rename multiple computers:

a. Create a csv file with a set of computer names targeted for renaming:

SERVER001,AWS-SERVER001
SERVER007,AWS-SERVER007
SERVER898,AWS-SERVER898

b. Run this script

$adminID = "KIMCONNECT\"+ Read-Host "Enter the admin username"
$pass = Read-Host 'Enter the admin password' -AsSecureString

function renameComputers{
    Write-Host "Importing Computers from CSV file"
    $renameList = Import-Csv "C:\scripts\rename.csv" -Header @("old","new")
    foreach ($item in $renameList) {
    	
    	# Test the input string to skip null values
    	if !([string]::IsNullOrEmpty($item.old) -or [string]::IsNullOrEmpty($item.new)){
		$oldName = $item.old;
		$newName = $item.new;
		Write-Host "Renaming computer from: $oldName to: $newName";
		netdom renamecomputer $oldName /newName:$newName /uD:$adminID /passwordD:$pass /force /reboot
    	} #endif
}
