=====Script=====Displays Computer Name
Option Explicit 
 
Dim Text, Title
Dim WshNetwork         ' Object variable
Text = "Networking information" & vbCrLf & vbCrLf
Title = "Rename Hostname?"
 
' Create a new WshNetwork object to access network properties.
Set WshNetwork = WScript.CreateObject("WScript.Network")
 
Text = Text & "Computer name : " & WshNetwork.ComputerName & vbCrLf
Text = Text & "Domain : " & WshNetwork.UserDomain & vbCrLf
Text = Text & "User name : " & WshNetwork.UserName & vbCrLf
 
MsgBox Text, vbYesNo + vbQuestion, Title
 
=====End=====
 
=====Script=== Prompting user to rename or not
 
strComputerName = InputBox("Enter a new machine name for this computer:", "Rename Computer")
Set objWMIService = GetObject("winmgmts:" & "{impersonationLevel=impersonate}!\\" & "." & "\root\cimv2")
Set colComputers = objWMIService.ExecQuery ("Select Name from Win32_ComputerSystem")
For Each objComputer in colComputers
      intErrorCode = objComputer.Rename(strComputerName)
      If intErrorCode <> 0 Then
            MsgBox "Error renaming computer. Error # " & intErrorCode
      Else
            Set objOutputFile = objFSO.CreateTextFile(strRenameFlag, True)
            objOutputFile.Close
            Set objOutputFile = Nothing
            MsgBox "Computer renamed. It will now reboot."
            objShell.Run "rundll32 shell32.dll,SHExitWindowsEx 2", 1, False

What does it mean to be "Always On"?

Is your cloud always on? With an Always On cloud you won't have to worry about downtime for maintenance or software application code updates, ensuring that your bottom line isn't affected.

You are getting the error code 5 because of the split token in windows 7. if you elevate the scripts privileges it should allow you to change the computers name.

This should work.
