10 things you should know about working with NTFS permissions

NTFS and share-level permissions both affect the user's ability to access resources on a network, and you need a good understanding of both types to untangle and resolve certain access issues. These tips and best practices will help you avoid some typical problems.

Managing and troubleshooting permissions can be challenging, especially when everything looks like it should work. These tips and best practices will help you avoid some common problems.

#1: NTFS vs. share permissions

The biggest point of confusion about sharing with Windows systems is that the NTFS and share-level permissions both have an effect on the user's ability to access resources on a network. This is especially important to remember for Windows XP and Windows Server 2003--and likely subsequent versions of Windows--which have default share permissions as read-only. This makes the NTFS permissions limited to read when accessing them over the network.

The best way to distinguish share permissions from NTFS permissions is to consider share permissions as an entry point to the resources. Only after the share permissions offer Change and/or Full Control can the NTFS permissions of that type be used.

The combination of share-level and NTFS permissions can seem like administrative overhead, but consider this: Share permissions act as a point of entry for the NTFS permissions over the network. When you enter a network resource through a share, the share permissions dictate what you cando through the share as a whole. The NTFS permissions dictate what you can do to specific files and folders. In the troubleshooting mode, identify whether share-level permissions can be ruled out of the issue. 10 things you should know about working with NTFS permissions
