DNS, Windows Event Log, AD Web Services not starting on Windows 2008 R2 DC



When you try to start the Windows Event Log service from the Services console on Windows Server 2008, the Windows Event Log service fails. Additionally, you receive the following error message:

Error 5: Access denied

The Task Scheduler and Windows Event Collector services, which depend on Windows Event Log service, also fail.


This problem happens if any of the following conditions are true:

  • The built-in security group EventLog does not have permissions on the folder %SystemRoot%\System32\winevt\Logs
  • The Local Service account does not have default permissions on the following registry key:



Restore the default permissions on %SystemRoot%\System32\winevt\logs.

Authenticated user – List folder/read data, Read attributes, Read Extended attributes, Read permissions

  2. Select the Security tab.
  3. Click Edit button and click the Add button in the permissions dialog box.
  4. In Select users, computers, or Groups dialog box ensure that under object types Built in Security Principals and the location as local computer name is selected.
