Error Codes 8004 Series HomeError Codes 8004 Series

Errors beginning with 8004xxx point to a WMI (Windows Management Instrumentation) error in your VBScript.

Error Code 8004 Series - Mainly WMI



Example Error Code 80041021

Windows Script Host Message Error Code 80041021 WMI VBScript

The script does not manipulate the WMI object as you had hoped, instead you get a Windows Script Host error message like this picture:

Case 1

Your VBScript contains a misspelled object name.  Code 80041021 is an unusual Error in that a number is returned rather than 'Syntax Error' or other message.  In my example the fault was in a WMI script, the cause was a syntax error with Set objWMI = GetObject("winmgmts:"

Set objWMIService = GetObject("winmgmts:" _
& "{impersonationLevel=impersonate}!\\" _
& strComputer & "\root\cimv2")

Set objWMIService = GetObject("winmgmts:" _
& strComputer & "\root\cimv2")

The Solution

I solved this 80041021 error message by paying close attention to the line number.  In addition, I compared the scripts to other WMI examples.  In one case it turned out to be a missing \\ in Set objWMI = GetObject("winmgmts:\\".....  In another case it was a missing & "{impersonationLevel=impersonate}!\\" _

If you are stuck try a parallel troubleshooting approach

Suppose that your mission is to create a WMI script which interrogates Win32_ComputerSystem, but the script just won't work.  Instead of going around in circles, try substituting a different Win32_Object.  If that also fails, look for a common cause, for instance, the fault with:

GetObject("winmgmts:" & "{impersonationLevel=impersonate}!  By trying a parallel approach you can isolate the error.  See more general troubleshooting ideas
