title: sql server installation errors regarding WMI service
body: <p>I am trying to install SQL Server 2008 and during the pre requisite check its always fails on 
  WMI service "Failed".
  I went to the event viewer and found this error in there.
  "Failed to Initialize WMI Core or Provider SubSystem or Event SubSystem with error number 0x80040154. This could be due to a badly installed version of WMI, WMI repository upgrade failure, insufficient disk space or insufficient memory."</p>
  
  <p>I know there is a lot of space available in my hard drive. Also i tried a few things after googling like WMIFIX.bat file. The file ran fine but did not fix the problem.
  Has anyone had this problem? If so do you have a solution?</p>
