Initially have a Z10Pro and I can see both the HDD and attached external fine under Network/ZD_SAMBA/Share in file explorer through Ethernet. Recently purchase a UHD5000 and attached to network as well but do not see it. Anything I need to do special to see both. (maybe server name change on UHD5000?) Not worried about them seeing each other, just need to get to the HDD's via File Explorer.
Have to explain the Netbios thing. I can see between the 2 zidoos and even play a file from one another. So its something between the PC and the new unit.
When you switch on the Samba server you need to give each one a unique name otherwise other devices will get confused if they use the name for network discovery: eg:
