Using powershell, how can I extract the OU path for a computer currently in AD?

I've managed to isolate the Distinguished Name, but I want to get rid of the Common Name part and only have the OU path. The length of the computer name will change depending on the pc, so I want to be able to only keep everything listed after the first comma (if that makes sense). It should work regardless if the PC name is 8 characters or 12 characters. This is what I have so far.

$testingThis = Get-ADComputer -Identity "ComputerExample" -Properties DistinguishedName | Select-Object -ExpandProperty DistinguishedName

Write-Output $testingThis

This is the output:

CN=example,OU=example,OU=example,OU=example,DC=madeup,DC=madeup,DC=madeup,DC=madeup

If I understand you correctly, you want to get only the OU where the machine is located.

You can do this:

$dn = $testingThis -split ',', 2
$dn = $dn[1]
$dn

or use an function to do that

    function Get-ComputerOU {
    param (
        [string]$ComputerName
    )

    # Get the Distinguished Name (DN) of the computer from Active Directory
    $Computer = Get-ADComputer -Identity $ComputerName -Properties DistinguishedName

    # Check if the computer was found
    if ($Computer -ne $null) {
        # Split the DN and return only the OU part
        $OUPath = ($Computer.DistinguishedName -split ',', 2)[1]
        return $OUPath
    } else {
        Write-Output "Computer not found."
    }
}

# Example usage
Get-ComputerOU "Computername"
