    Problem accessing a NAS drive


    I have 2 NAS drives and 3 computers in my home network. The NAS drives and one PC are Ethernet-connected to a router/wireless access point; the other 2 PCs use wireless connections. All 3 PCs can access one NAS drive with no problem. The drives show up in the Network section of File Explorer, and if I click on the NAS's icon all it's shares are displayed (whether or not the PC has credentials to access the shares). The shares on the other NAS drive can be seen by only 2 of the PCs.

    On the failing PC the inaccessible NAS drive shows in File Explorer, but if I click on it I get

    However, on that same PC, Firefox can access the FTP server on the NAS drive

    so Windows obviously has no trouble communicating with the NAS. And Windows must be configured to allow communication with a NAS in general or it could not successfully connect to the other NAS. (Those two screen snips were stored on that working NAS.)

    The problematic PC doesn't really have to reach the NAS, but I would like it to, and I'm frustrated that I can't figure this out. Anyone have any suggestions?

    BTW, the error popup says I should ask the administrator of the server about this. I would, but I'm not speaking with myself at the moment.

    The Western Digital My Clouds have been an issue for a very long time, way before Windows 10 rolled out.

    I'll check that out. I'm thoroughly confused about NetBIOS in a Samba environment. I thought with Windows using SMB over IP (TCP and UDP ports 445) that NetBIOS was no longer needed, but I seem to have problems if I disable NetBIOS. Maybe I have it disabled on the problematic PC.

    SAMBA is the technology that is used for connecting to Windows and other network systems. NetBios tells windows machines and Samba on LInux & Unix systems how to know how to communicate.

    "NetBIOS was developed in 1983 by Sytek Inc. as an API for software communication over IBM PC Network LAN technology. On PC-Network, as an API alone, NetBIOS relied on proprietary Sytek networking protocols for communication over the wire. Because PC Network only supported up to 80 devices in its most accommodating mode (baseband), NetBIOS was itself designed with limited nodes in mind."

    Windows is so tightly wound with old tech, that because Netbios is embedded in the OS, along with their version of Samba, one thing breaks, everything breaks.
