NTFS Permissions Inheritance Changes in Windows Vista, 2008, and 7
If you haven’t studied NTFS permissions in the past few years then that means not only do you need to update your MCSE, but you need to be aware of one change in a fundamental inheritance rule.
Previously, when moving a file or folder to another location on the same physical disk, the file/folder would retain the permissions from its original location. This changes when Windows Vista was released and had remained changes in Windows Server 2008 and Windows 7. Now, a file/folder will automatically inherit the permissions of its new location when being moved to a new location on the same physical disk.
