SQL Server Configuration Manager – Cannot connect to WMI provider

I was trying to access my SQL Server 2008 R2 Network Configuration to enable Tcp/Ip connections to my server through the SQL Server Configuration Manager from the Configuration Tools. But suddenly an error message appeared indicating that I can’t access my configuration manager through the WMI provider. The error message that popped up is shown down below:

 

 

As we can see above, the error pop up dialog indicates that I don’t have the permission to access the server or it’s unreachable. But SQL Server is already installed properly on my machine and I can access the instance through the Microsoft SQL Server Management Studio. So, why this error occurred ?

This error occurs when the .mof files (Microsoft Object Format) are damaged or not properly installed and registered during the MS SQL Server 2008 R2 installation process.

In order to solve this issue, we have to do the following steps:

1. Run the command prompt as administrator.
2. Change the directory to the following path: “C:\Program Files (x86)\Microsoft SQL Server\100\Shared”.
3. Use the mofcomp.exe to register the .mof file again by running the following command: mofcomp.exe “C:\Program Files (x86)\Microsoft SQL Server\100\Shared\sqlmgmproviderxpsp2up.mof”

Remark: mofcomp.exe is used to compile Managed Object Format (MOF) code into binary form stored in the WMI repository. Use when creating or modifying the MOF file for a WMI provider. mofcomp.exe is one of the WMI Command Line Tools in Windows.

Now the MOF file in SQL Server 2008 R2 is parsed successfully and the SQL Configuration Manager will execute without any error.
