Audit the local Administrators group on a list of remote computers

Posted by Jean Louw

This is a very basic script which collects a list of server names from a local text file called servers.txt. The script reports the list of users, sorted by server name to a local text file in the root of drive C. I am working on cleaning up the results, as currently the "Adspath" reports to the text file in the following format: WinNT://DOMAIN/COMPUTER/Administrator This was the only true distinction between local or domain users, as "Name" reports only the name of the user or group. So you are never really sure if it is a domain or local entry. Finally I need to enable the script to report its results to Excel or HTML.

$Result = @()

foreach($server in (gc .\servers.txt)){

$computer = [ADSI](”WinNT://” + $server + “,computer”)
$Group = $computer.psbase.children.find(”Administrators”)

function getAdmins
{$members = $Group.psbase.invoke(”Members”) | %{$_.GetType().InvokeMember(”Adspath”, ‘GetProperty’, $null, $_, $null)}
$members}

$Result += $server
$Result += ( getAdmins )
$Result += " "
}

$Result > c:\results.txt
Invoke-Item c:\results.txt

I had a little extra time today, and managed to clean up the members using the -replace parameter, replace "DOMAIN" with your domain name. The updated code looks something like this:

$Result = @()

foreach($server in (gc .\servers.txt)){

$computer = [ADSI](”WinNT://” + $server + “,computer”)
$Group = $computer.psbase.children.find(”Administrators”)

function getAdmins
{$members = ($Group.psbase.invoke(”Members”) | %{$_.GetType().InvokeMember(”Adspath”, ‘GetProperty’, $null, $_, $null)}) -replace ('WinNT://DOMAIN/' + $server + '/'), '' -replace ('WinNT://DOMAIN/', 'DOMAIN\') -replace ('WinNT://', '')
$members}

$Result += Write-Output "SERVER: $server"
$Result += Write-Output ' '
$Result += ( getAdmins )
$Result += Write-Output '____________________________'
$Result += Write-Output ' '
}



$Result > c:\results.txt

Invoke-Item c:\results.txt

You can simply add another -replace ('WinNT://DOMAIN/', 'DOMAIN\') for each domain in the system. I know its a little hack 'n slash but it will do for now.
