Given what's in the Win10 thread, at least 2 users experienced the same problem where the security policy edit "fixed" it (so to speak).
In any case, setting a hosts file entry should completely negate the host name to IP address mapping issue, if the OS utilized it as the override/user defined default it was originally intended to be.
Each of the hoops, in that oversized how-to, addressed at least one potential issue that blocked access to SMB shares, at some point in time
The option I posted just works, and working on the KISS principle I would have thought would be a suitable option for most users. What they complain about is the fact that OMV or any other Linux distro using SMB just doesn't show up in File Manager -> Network. They're not interested in the techno stuff they want a solution -> yesterday, and they assume because they use Windows it's not that that is at fault!
Sorry that was a rant.
