Windows sharing vs security tabs

Spent 5 hours trying to connect user to a network share, forgot Sharing vs Security in windows.

Short answer:  setup SHARING first, for additional control (eg  not all files with same permissions) then use Security via NTFS.

Some details from HowtoGeek:

Share Permissions:

1. Only apply to users who access the resource over the network. They don’t apply if you log on locally, for example through terminal services.
2. It applies to all files and folders in the shared resource. If you want to provide a more granular sort of restriction scheme you should use NTFS Permission in addition to shared permissions
3. If you have any FAT or FAT32 formatted volumes, this will be the only form of restriction available to you, as NTFS Permissions are not available on those file systems.

NTFS Permissions:

1. The only restriction on NTFS Permissions is that they can only be set on a volume that is formatted to the NTFS file system
2. Remember that NTFS are cumulative that means that a users effective permissions are the result of combining the user’s assigned permissions and the permissions of any groups the user belongs to.
