how can get all list of local administrator accounts and enabled computers on network?

You can't, really, unless you can be sure that all computers are in AD, in which case, Get-ADComputer.

Yes all computers are in AD, I was using
Get-ADComputer -Filter * -Property * | Format-Table Name , Enabled -Wrap –Auto
but it shows me just list of computer, i also need local administrator accounts

This code i was trying, but not working. I am new in Powershell

Import-Module ActiveDirectory

$ADComputerArray = Get-ADComputer -Properties * -Filter * -SearchBase "OU=LocalAdministrators, DC=domainname,DC=ad"

foreach($ADComputer in $ADComputerArray){

$GroupMembers = Get-ADComputerMember $ADComputer
$file.WriteLine($ADComputer.Name + ":")

foreach ($member in $GroupMembers){
if ($member.objectClass -eq "user"){

It appears that you are coming from a background in VBScript trying to write a file on the fly. A more 'Powershelly' way to do it is working with objects and then exporting them to a file. The code you posted looked like you were trying to get AD computer information. It sounds like you want the members of the local administrator group on a computer. You can try the below which is something I modified to from this function.

function Get-LocalAdmin {  
    param (
        $ComputerName = $env:COMPUTERNAME
    if (Test-Connection -ComputerName $ComputerName -Count 2 -Quiet) {  
        try {
            $admins = Get-WmiObject -Class Win32_GroupUser -ComputerName $ComputerName -ErrorAction Stop |
            Where {$_.GroupComponent –like '*"Administrators"'}
            $localAdmins = foreach ($admin in $admins) {
                $admin.partcomponent –match “.+Domain\=(.+)\,Name\=(.+)$” > $nul  
                $matches[1].trim('"') + “\” + $matches[2].trim('"')  

            $props = @{
                ComputerName = $ComputerName
                LocalAdmins = $localAdmins
                Status = "Success"
        catch {
            $props = @{
                ComputerName = $ComputerName
                LocalAdmins = @()
                Status = "Failed. WMI Error connecting to {0}. {1}" -f $ComputerName, $_.Exception.Message
    else {
        $props = @{
            ComputerName = $ComputerName
            LocalAdmins = @()
            Status = "Ping Failed. {0} is offline." -f $ComputerName

    New-Object -TypeName PSObject -Property $props

$computers = Get-ADComputer -Properties * -Filter * -SearchBase "OU=LocalAdministrators,DC=domainname,DC=ad"

$results = foreach($computer in $computers){
    Get-LocalAdmin -ComputerName $computer.Name



PS C:\WINDOWS\system32> Get-LocalAdmin

Status  ComputerName LocalAdmins                       
------  ------------ -----------                       
Success MY-PC       {MY-PC\Administrator, MY-PC\Rob}

Once you have the results, you would export them to a CSV or better yet use Powershell to run queries against the $results:

$results | Select Status, ComputerName, @{Name="LocalAdmins";Expression={$_.LocalAdmins -join ","}} | Export-CSV C:\Scripts\LocalAdmin.csv -NoTypeInformation

Thank you very much, it helped me a lot
But is it possible to get list of all computers on AD and return list of local administrator accounts and the enabled\disabled status of those accounts using one script

ComputerName Status Local Administrator
