How can I resolve a "Provider load failure" for WMI requests?

I'm using WMI to collect system information. It works fine on every system I've tested it on, but I have one or two users that are reporting problems. The debug logs show the WMI code is throwing a "Provider load failure" exception. I haven't been able to replicate the issue.

The users have verified that the WMI service is running in Automatic mode.

Here's the exception:

System.Management.ManagementException: Provider load failure 
   at System.Management.ManagementException.ThrowWithExtendedInfo(ManagementStatus errorCode)
   at System.Management.ManagementObjectCollection.ManagementObjectEnumerator.MoveNext()

Any thoughts on how to troubleshoot and resolve this issue?

c# .net wmi

One way to possibly track down the root cause of the issue is to use WBEMTest a tool that the MS Scripting Guys say is one of the easiest ways

"To find the provider of a WMI class..."

The Scripting Guys: Use PowerShell to Troubleshoot “Provider Load Failure”

The high level steps specific to the Win32_NetworkAdapter are described in this Win32_network adapter "provider load failure" post by Mark Wolzak at infoSupport.

Click start >> run >> wbemtest
click 'Connect…' to connect to a namespace
execute the query 'Select * From MSFT_WmiSelfEvent'
scroll down to the bottom and trace the following WMI events
Look at the details of any Msft_WmiProvider_InitializationOperationFailureEvent or Msft_WmiProvider_LoadOperationFailureEvent for the dll that is causing the issue

Thanks to the WMI–Provider Load Failure post at Richard Siddaway's Blog for pointing me to this tool and specific methodology.
