Domain vs Workgroup - rename

[MadBoy]

Hello,

I've been searching for solution to know if Computer is in Workgroup or Domain and what's Workgroup name or what's Domain Name. I found WMI call that can be used for that but...

$Output = $Output & "Domain: " & $objItem.Domain & @CRLF

that returns name of Workgroup too. So i thought about checking for @LogonDomain if @logondomain = @computername then you know WMI name it returns is Workgroup. Otherwise it will be domain. But now what if i would like to change that Workgroup to other name? How to do it? And how to do it if i want to join computer to domain (and i would like to do it without netdom.exe)? Any hints?

$wbemFlagReturnImmediately = 0x10
$wbemFlagForwardOnly = 0x20
$colItems = ""
$strComputer = "localhost"

$Output=""
$Output = $Output & "Computer: " & $strComputer  & @CRLF
$Output = $Output & "==========================================" & @CRLF
$objWMIService = ObjGet("winmgmts:\\" & $strComputer & "\root\CIMV2")
$colItems = $objWMIService.ExecQuery("SELECT * FROM Win32_ComputerSystem", "WQL", _
                                          $wbemFlagReturnImmediately + $wbemFlagForwardOnly)

If IsObj($colItems) then
   For $objItem In $colItems

      $Output = $Output & "Domain: " & $objItem.Domain & @CRLF
      $Output = $Output & "Workgroup: " & $objItem.Workgroup & @CRLF
      
      if Msgbox(1,"WMI Output",$Output) = 2 then ExitLoop
      $Output=""
   Next
Else
   Msgbox(0,"WMI Output","No WMI Objects Found for class: " & "Win32_ComputerSystem" )
Endif
