Resolution:

Upon investigation, I found that the Windows Event log service was also not started. Attempt to start the service would fail with error Access is Denied. So, I used Process Monitor (Procmon.exe), ran it and reproduced the issue with Windows event log service again.

  • The Local Service account did not have Write privilege on folder C:\Windows\System32\winevt\Logs
  • Granted Local Service account Write privilege on the above mentioned folder.
  • Started the Event log service successfully and started the DNS service successfully.

Below is the screenshot of ProcMon output with filter to display result containing Access denied
