PowerShell
1

Here is a easy way to see who’s part of a local admin group remotely on a server or another machine. This is compatible with Server 2008 R2+.

CLS

$Server = "serverABC"

Invoke-Command -ComputerName $Server -ScriptBlock{
   $members = Invoke-Expression -command "Net Localgroup Administrators"
   $members[6..($members.Length-3)]
}

Here is an example of how you can use this to copy all the members of a Local admin group on server1 and replicate that same structure on server2

$CopyServer = "Server1"
$NewServer = "Server2"

$LocalAdminUsers = Invoke-Command -ComputerName $CopyServer -ScriptBlock{
   $members = Invoke-Expression -command "Net Localgroup Administrators"
   $members[6..($members.Length-3)]
}

Invoke-Command -ComputerName $NewServer -ScriptBlock{
    
    foreach($user in $using:LocalAdminUsers)
    {
        Invoke-Expression -command "Net Localgroup Administrators $($user) /add" -ErrorAction SilentlyContinue
    }

} -ErrorAction SilentlyContinue
