WMI–Provider Load Failure

I’m currently writing Chapter 11 of PowerShell and WMI and its about using the WMI classes related to networking. I tried the Win32_NetworkAdapter on the HP laptop I use for writing and everything worked fine. Tried it on my Lenovo that I use as a Hyper-V server and got a Provider Load failure error.

PS> Get-WmiObject -Class Win32_NetworkAdapter
Get-WmiObject : Provider load failure
At line:1 char:14
+ Get-WmiObject <<<<  -Class Win32_NetworkAdapter
    + CategoryInfo          : InvalidOperation: (:) [Get-WmiObject], ManagementException
    + FullyQualifiedErrorId : GetWMIManagementException,Microsoft.PowerShell.Commands.GetWmiObjectCommand


This is definitely in the realms of not good. At this point I was imagining WMI rebuild or even a complete server rebuild.

I tried

Get-WmiObject -Class Win32_NetworkAdapterConfiguration


and it worked. Now that’s confusing.

Did a Bing search and found this post

which walks through how to use wbemtest to see what is happening.

Turns out like the author of the post I had the Intel WiFi tools installed but didn’t have an Intel wireless card. The LAN card is Intel so I guess that’s where the tools came from.  The wifiwmip.dll seems to be to blame for the problem. 

Removed the intel WiFi tools and everything now works.
