Error code: 4201 - The instance name passed was not recognized as valid by a WMI data provider.

    Question

  • Got the Error code: 4201 when attempting to start the Windows Event Log.

    I am almost certain that it has something to do with me changing ownership in the C:\ directory so that I could access C:\Documents\User\SendTo folder.

  • I figured it out.

    I didn't have the Permissions or the Auditing set correctly.

  • I forgot to mention that in trying to delete some .jpg files in the Windows\Web directory I wound up taking ownership of the subfolders in order to successfully delete them.

    I can't think of anything else that could have resulted in that Event Log/WMI error.   All I have installed is Win 7 x64, the regular Windows Updates and some other recommended updates (drivers for my VGA, NIC, HID, TV tuner...I think that's it).  All were done via the Windows Update program.

    I don't think it was any of the many settings that I made via the MMC/Local Computer Policy.  Most of the changes were for Internet Explorer.  Made some minor settings for Windows Explorer, Windows Installer, Windows Messenger, etc...

    Any advice would be greatly appreciated.

  • Can you clarify what exactly you did to solve this? Where did you not have Permissions and Auditing set correctly? How did you set them?

    I'm having the same problem. Thanks in advance.

  • Ya, I'm having the same thing happen. Just started after running the final release of Win 7 now for about 6 weeks. I had also changed permissions to get some things to work so that could be it. Could you give some direction on what you did to rectify?
