Cannot connect to SMB shares on Windows 10

I recently set up a new Windows 10 machine. After eight years with only Apple devices, I finally wanted to fetch up with the PC and Windows world again.

For a day or two, I tried to connect my laptop to my NAS at home. I checked firewalls, credentials, server settings, usernames, network. I checked it double, triple, quadrupplewise. I tried almost any permutation. Eventually, I gave up.

The actual problem was, Windows 10 gave no feedback at all when trying to connect to a SMB (aka Sever Message Block Protocol) share on my server. All connection attempts just ended with a silent fail. In terms of user experience this is a violation of Grice’s maxims. Windows 10 simply chooses to opt out of the conversation.

At a very last attempt, I tried the option to map a network drive. After entering user credentials again and again, finally Windows 10 came up the very first time with a useful error message.
