I have another file server, in a different domain, with a nearly identical
smb.conf to this one, which does not have an entry for "smb encrypt".
According to the man page, this means that it will have "smb encrypt =
default".  W10 clients are not able to connect to shares, by name, on this
file server,  after having been idle overnight.  This is the same behaviour
that I was seeing in the other environment where I recently set "smb
encrypt = off".  I think this is fairly clear evidence that there is a bug
(either with the W10 client or with the samba file server).  Again, I'm
happy to file a bug report with samba's bug tracker if you think this is
the best course of action.
