I'm using Ubuntu server as my NAS and is connecting and mapping drives successfully through, XP Vista, Win 7 Win 8.1.
Lately I've installed Windows 10 Pro on to another PC which after the installation completed I can also map drives successfully. Then windows 10 downloaded the latest update/upgrade to Windows 10, Version 1511, build 10586 and suddenly the Ubuntu server will not appear in the windows network window and neither can I map any drives.
I've tried installing earlier and later versions of the network device driver but to no avail.
I'm running Zone-Alarm Pro on all my machines and cannot blame the Zone-Alarm software because I can access the Ubuntu server and map drives on other machines successfully not running Windows 10.
