NTFS File Permissions
When you copy or move a file or folder to another volume, the object inherits the permissions of its new folder. This setting allows you to force Windows to preserve the current permissions instead.
Open your registry and find or create the key below.
Create a new DWORD value, or modify the existing value, called "ForceCopyAclwithFile" and set it according to the value data below.
Exit your registry, you may need to restart or log out of Windows for the change to take effect.
Note: By default, an object inherits permissions from its parent object, either at the time of creation or when it is copied or moved to its parent folder. The only exception to this rule occurs when you move an object to a different folder on the same volume. In this case, the original permissions are retained.
The registry key you want to add/or modify is:
[HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\Explorer]ForceCopyAclwithFile
REG_DWORD (DWORD Value)
Value Data: (0 = default, 1 = preserve original permissions)
Best of luck with that issue.
