Restricting root permissions

Posted on 2014-03-04
Last Modified: 2014-03-27
Dear Experts,

We would like to restrict the permissions on the root level folder of our shared drive so that users cannot save files directly to the root anymore. At the moment we have:

Domain Admins - Full Control - This folder, subfolders and files
Domain Users - Read, write & execute - This folder, subfolders and files
SERVER\Users - Read & Execute - This folder, subfolders and files
SYSTEM - Full control

How do I accomplish this without affecting the folders below some of which do not inherit permissions?

Go to advance security permissions and change it...
Make sure do not inherit or replace permission is selected.

DON'T do that.  You'll deny Administrators too and EVERYONE including the system account.  Your pagefile will error out and your hibernate file and all your other hidden system files will start generating errors.

It's actually best not to use deny unless you're sure that's exactly what you want.  It's better to remove permissions.  Remove Domain Users from the permission list instead.  Be sure that Domain Users still exist in the subfolders that need it.  Make sure you don't propagate the removal to the subdirectories.

Remove Domain Users from the permission list instead.

if you remove domain users from the ACL, they will get access denied when just trying to reach the root of the drive unless they are a domain admin

if you change the domain users permissions by only selecting these items for 'this folder only ' then it should work; they can see everything but can't write to the top-level folder

traverse folder / execute file
list folder / read data
read attributes
read extended attributes
read permissions

@serialband, My intention is to show, how to deny to create the files on DATA/root folder as per author request  not SYSTEM DRIVE.  (now i realized that you are referring my screenshot)

Is it best practice to remove the SERVER\Users account and just use 'Domain Users'?

The users will need to be able to create folders just not be able to write files to the root.

So if I use the permissions suggested by Seth but also add Create Folders this should accomplish what I need right?

Seth Simmons is right.  I just saw the deny everyone screenshot and responded quickly, because I saw a disaster about to happen.  No matter what the situation, you don't deny unless you have a very good reason or have exhausted other options.  It's still far better to uncheck the permissions rather than deny them.  You're more likely to run into problems later on if you deny permissions without some planning.  There's already an implicit deny when you're not in the permissions list.

You might also want to uncheck the 5 checkboxes directly below the highlighted section in the image that sgupta1181 provided if you also don't want them to modify the permissions and edit the files.
Create olders/append data
Write attributes
Write extended attributes
Delete subfolders and files

So essentially I've removed Create files / write data from Domain Users (This folder only) and had to add another entry for domain users (subfolders and files only) to give them read, write & execute
