I am having trouble connecting to my WD My Cloud 2TB over the LAN through Network (Windows), but I can access it via HTTP. So this seems like a Windows problem. I have enabled NETBIOS over TCP/IP from the network card settings as described in various forums but its still no go. I have no Firewall or Antivirus blocking the connection.
How long has this been happening and how are you trying to connect to your My Cloud? Are you trying to open it through File Explorer or a WD My Cloud app? Does it have the same workgroup name as your computers?
The problem is occuring after the unit goes to sleep mode.
I am trying to connect via Windows File Explorer (aka Network Neighborhood). Yes, they are all in the same workgroup. (It also connects OK with WD Cloud app).
Weirdly what I lately discovered is, I can connect if I write the IP address to the Explorer Address bar such as \10.0.x.x
Problem usually resolves temporarily when I restart the Windows machine. But after a while it repeats again. Yes, I am guessing its a Windows problem, but I would like to know the reason. Never ran into such problem with Windows7.
I have Windows 10 too with all updates and here is what I get when using File Explorer>Network. See image below.
