Sometime while connecting to MSSQL Server Configuration Manager it throws following Error
Cannot Connect to WMI Provider. You do not have permissions of the server is unreachable. Note that you can only manage SQL Server 2005 servers with the SQL Server Configuration Manager. Invalid namespace[0x8004100e]
I have searched on Google and found that it happens when 32bit MSSSQL application is installed on 64bit Server and they suggested to execute the following command to fix the issue.
mofcomp "%programfiles%\Microsoft SQL Server\90\Shared\sqlmgmproviderxpsp2up.mof"
