Best Practices on Combining NTFS and Share Permissions

The best way to go about combining NTFS and Share permissions is to first understand how the two types of permissions affect one another. In fact when NTFS and Share permissions are combined, the most restrictive permission will take effect.

The best approach to minimize the confusion and difficulty of combining NTFS and share permissions, is to always assign the user entity of “Everyone” “Allow-Full Control” share permission and then assign more detailed permissions using NTFS permissions. This way we have avoided the difficulty of combining permissions effectively and have also managed to provide more detailed permissions to users and groups.
