If you want to know the local admins in workstations and servers in your company / OU, you must copy my script to Windows PowerShell ISE and Run As Administrator.
#Make your own computers list and save it in your desktop with computers.txt name and format
$servers = Get-Content ‘C:\Users\%username%\Desktop\computers.txt‘
$output = ‘C:\Users\%username%\Desktop\finish.csv‘
$results = foreach ($server in $servers) {
$group = [ADSI]”WinNT://$server/Administrators”
$group.Invoke(‘Members’) | % {
$path = ([adsi]$_).path
[pscustomobject]@{
Computer Name = $server
Domain / Local = $(Split-Path (Split-Path $path) -Leaf)
User = $(Split-Path $path -Leaf)
}
}
}
$results | Export-csv $Output -NoTypeInformation
#Check your Desktop and check your finish.csv file after finished process of script
