Apart from multiple default lines, there doesn't seem to anything really 
wrong with your smb.conf, so it looks like this could be yet another 
reason to not use Windows 10 with an NT4-style PDC.

You could try raising the log level, add 'log level = 10' to the 
smb.conf and restart Samba, but beware, this will lead to a lot of output.
