Mongod 7 windows service refuses to start after Authorization enabled

After creating admin user and changing Authorization to enabled, mongodb service does not start with the message:

Can someone help?

Check your config file again
Do not use tab but use space bar
Most likely Yaml indentation issue

I had already read and applied what you said, but no change…

Check two places for errors:

  1. Windows EventViewer
  2. MongoDB Logs
