When Node Access doesn't work correctly- Drupal 7 Modules

Had the issue that I enabled Node Access but it was still allowing unauthenticated user to view content that should should have no access to.  There are a couple of ways to go about fixing this.

1.Run the Status Report and look half way down the page to the Node Access Permissions section. There is a 'Rebuild Permissions' link there. This function can take a long time if you have a lot of content.  This worked for some but not all users.

2. Admin > Structure > Content Type > pick the content type and click the Access Control tab
- Under the Advanced section at the bottom, bump it up to 10.  This worked for me.
