Recently, I had an issue where I installed SQL server with the default users to start the services. Later when I tried to change the service accounts to my active directory accounts, I got the following error message when trying to open SQL Server Configuration Manager.
I read that message “Cannot connect to WMI provider. You do not have permission or the server is unreachable. Note that you can only manage SQL Server 2005 and later servers with SQL Server Configuration Manager. Invalid class [0x80041010]” a few times and then I went to my favorite search engine Bing to find the answer.
I found this article right away: Error message when you open SQL Server Configuration Manager in SQL Server: “Cannot connect to WMI provider. You do not have permission or the server is unreachable”
The reason that this problem occurs is due to the fact that I installed a 32 bit version of SQL Server (for testing) on a 64 bit OS. The problem is that SQL Server 2008 is always installed for both SQL Server 2012 and 2014 to help maintain backward compatibility to help with easier migrations of old SQL Server instances. Then it will open up the problem, because the WMI provider is removed when you uninstall an instance of SQL Server. (Both the 32-bit instance and 64-bit instance of SQL Server will share the same WMI configuration file. (This file is located in the %programfiles(x86)% folder)
To work around this problem, open a command prompt, type the following command, and then press ENTER:
mofcomp “%programfiles(x86)%\Microsoft SQL Server\number\Shared\sqlmgmproviderxpsp2up.mof”
Note: For this command to succeed, the Sqlmgmproviderxpsp2up.mof file must be present in the %programfiles(x86)%\Microsoft SQL Server\number\Shared folder.
The value of number (As seen below) depends on the version of SQL Server: number
This is the command that I ran on my SQL Server 2014 instance to resolve this issue:
mofcomp “%programfiles(x86)%\Microsoft SQL Server\120\Shared\sqlmgmproviderxpsp2up.mof”

Done!

After you run the Mofcomp tool, restart the WMI service for the changes to take effect. The service name is Windows management Instrumentation.
As usual, I hope this helps you!
