I'm trying to prevent folders moves, really folder delete in NTFS parlance, for series of folders within a network share.

So let's say I have: FolderA, FolderB, FolderC. Each folder has various files and subfolders. I want the Domain Users group to have modify access to all files and folders beneath FolderA, FolderB, and FolderC. However I don't want them to be able to delete these three top level folders.

The issue we are having right now is people keep accidentally dragging one top level folder into another.

I've tried used advanced NTFS permissions to deny domain users delete access to these top level folders, and set the permissions to apply to "This folder only", however it seems to only affect sub-folders, and not the top level.

Platform is Server 2008 Standard.

Thanks in advance.
