Windows Vista - Server Execution Failure/WMI Control



Symptoms of this issue may include:

  • Networking icon in system tray will display a red 'X', despite being connected to the internet
  • When moving the mouse over the system tray networking icon, a balloon message will appear saying "Connection status: unknown server execution failure"
  • Sound will not work, despite sound system tray icon showing volume control as working
  • Media files will not open/play
  • In Windows WMI Control, this is displayed:

    Failed to initialize all required WMI classes:
    Win32_Processor: Win32: Access is denied
    Win32_WMISetting: Successful
    Security information: Successful
    WIN32_OperatingSystem: Win32: Access is denied

    To access this go to Start --> Control Panel --> Administrative Tools --> Computer Management
    Open up 'Services and Applications,' then right click 'WMI Control,' and click 'Properties.'

    Eventually all these lead to various services and programs beginning to fail and forcing the computer to shutdown or run really slowly.

IMPORTANT NOTE: THE FIX BELOW IS NOT AN OFFICIAL FIX FROM MICROSOFT, WHICH MEANS IT MAY NOT WORK IN ALL SITUATIONS. IT WAS FOUND BY RESEARCHING THE PROBLEM THROUGH INTERNET FORUMS. PLEASE EXERCISE CAUTION WHEN USING IT. IT IS RECOMMENDED THAT YOU BACK UP ANY IMPORTANT DATA YOU MAY NEED AND SET A SYSTEM RESTORE POINT IN ORDER TO REVERT BACK TO A WORKING STATE IF THE FIX DOES SOMETHING THAT IT SHOULDN'T.

Solution:

To fix the networking issue as well as the server execution error, follow these steps:

  1. Right click 'Computer'
  2. Click 'Manage'
  3. Under the 'System Tools' section, double click 'Local Users And Groups'
  4. Click 'Groups'
  5. Right click 'Administrators'
  6. Click 'Add to group'
  7. Click 'Add'
  8. Click 'Advanced'
  9. Click 'Find Now'
  10. Double click 'Local Service'
  11. Click 'Ok'

    12. 'NT AuthorityLocal Service' should show up in the list now
  12. Click 'Ok'
  13. Close computer management and reboot
This can also be done through the command prompt. You must be in adminstrator mode to do this (Note: for Vista Home users, the command line prompt must be used in order for this to work correctly). To do this, Click Start --> All Programs --> Accessories, then right click on 'Command Prompt,' and click on 'Run As Administrator.' Once there type in the following command:

net localgroup Administrators /add Local Service

Now type in the following command:

net localgroup Administrators

If done correctly, you should see the window below. If the 'NT AuthorityLocal Service' line appears, then all is done correctly. Reboot your computer at this point.

success

If you type in the first command and see a window like the one below with the statement 'The syntax of this command is,' this means that you need to change the word 'group' to 'host.'

error

The new command you should enter will read:

net localhost Administrator /add Local Service

Then run the command:

net localhost Administrator

and make sure that you see the 'NT AuthorityLocal Service' line appear. Then reboot your computer.

To fix the WMI Control error, follow these steps:

Open up a command prompt as described above and type in the following command:

net localgroup Administrators /add Service

Then run the command:

net localgroup Administrator

and make sure that you see the 'NT AuthorityService' line appear. Then reboot your computer.
This command works the same as above. If you get the syntax error screen, just change the word 'group' to 'host' as described above. You should now go back to the WMI Control window as described above and check to see that the lines that said 'access denied' are gone. The window should now display some information about your computer's system and not have any kind of error message in it.
