Hi,
So far there have been over 60 reads on your post and no responses, so, I will just start by saying I might be missing your point, but...files once stored on the NAS are controlled by the user settings on the NAS only. The choices are basic, "read only, read and write, or deny access." File attributes only are active when the files are on the Windows machine in my understanding anyway. If I am totally missing your point, I am sorry, otherwise, good luck.
