On only this Win 7 Ultimate, 64bit machine I cannot save a webpage in any of the three options - webpage complete, Web Archive (Mht), or Web page HTML only. The saves work fine when saving to my C: drive but I save all my personal data on an NAS. When saving to the NAS from this particular machine it shows the progress bar as though it is saving, then flashes up the "This Web Page Could not be saved". The page is there and usually will open but not always and sometimes opening the page takes forever. I suspect something in the firewall is not set right and I need help on what to look for. When I go into the firewall for the private network I see pages and pages of rules. What rule should I look for specifically to allow web pages to be saved to my private networked NAS? Would it be an incoming or outgoing rule or would both be affected? My wife has another Win 7 (home premium) which saves web pages to the NAS ok, and I have a Win 8.1 netbook that has no problems saving web pages using IE10. Any ideas?
