My two LinkStations and a Terastation are visible in both "Network" and "Windows Network" but clicking on any of them results in "failed to retrieve share list from server". I have Ubuntu 16.04 LTS and samba is installed. All are in the same Windows workgroup. All have static IP addresses 192.168.1.xxx and the network connections are wired NOT wifi. smbtree actually shows all the shares on those three Linux-based NAS. All four Linux devices and their shares are visible and accessible from my Windows 7 Ultimate PC. Accessing my Windows PC from my Linux PC asks for a password, but that is a separate issue. Adrian
