Hi Ramesh,

That did the trick.  For the record:

  1. Used msconfig to switch to safe mode boot
  2. Booted to safe mode
  3. ran cmd.exe as an administrator
  4. typed "cd C:\Windows\System32\LogFiles\WMI"
  5. typed "rename RtBackup RtBackup2"
  6. Used msconfig to switch to normal boot mode
  7. Reboot and found event viewer working

Thank you! 

Rung

Hi rung_windows7,

Renaming or deleting the following folder seems to work for some users:

C:\Windows\System32\LogFiles\WMI\RtBackup

REF: Event log error 4201 - ERROR_WMI_INSTANCE_NOT_FOUND (a helluva great thread)

    Thanks a lot Ramesh.

    My VPN would not start overnight.

    It is correct the Event viewer would not start either.

    After renaming RtBackup all was solved.

    By the way had to take ownership of the File to change the attribute which would

    then allow me to rename RtBackup.

    Thanks again !
