When saving documents to NAS , Word Application keeps on asking to save the document again which in fact I have already choose Save before exiting Word Application. When opening the document too it's showing as read-mode only. Thou this issues randomly happens but when I checked and also reviewed internet there are other people who has the same issue. Another irritating issue is that it keeps on claiming that files are opened elsewhere when they do not appear to be which I made sure since the second machine that I have is turned off. The issue is not present when saving documents locally.
