SQL-Server

I'm getting the below message when i try and access SQL Config Manager on my Windows Server 2003 R2

"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.		
Generic failure [0x80041001]"

Also tries with the below solution but still the error persists
The solution is to go to a command prompt and then run mofcomp.
C:\Program Files\Microsoft SQL Server\90\Shared>mofcomp "C:\Program Files\Microsoft SQL Server\90\Shared\sqlmgmproviderxpsp2up.mof"

Below was the output of the command:

C:\Documents and Settings\Administrator>mofcomp  "%programfiles(x86)%\Microsoft
SQL Server\100\Shared\sqlmgmproviderxpsp2up.mof"

Can anyone tell how this problem can be solved?
