If you are getting this 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. Note that you can only manage SQL Server 2005 and later servers with SQL Server Configuration Manager. Invalid namespace [0x8004100e]
Then there is a simple fix for this. All you need to do is to open a command prompt as an administrator (run as administrator) and then run the following command:
mofcomp "%programfiles(x86)%Microsoft SQL ServernumberSharedsqlmgmproviderxpsp2up.mof"
Note that “number” should be the version of SQL that you are using. See the list below for the version numbers for SQL:
|Microsoft SQL Server 2012||110|
|Microsoft SQL Server 2008 R2||100|
|Microsoft SQL Server 2008||100|
|Microsoft SQL Server 2005||90|
Once you have run this command, you then need to restart the “Windows Management Instrumentation” service or reboot the machine with the problem.
After this you should then be able to successfully open the SQL Configuration Manager Console.
