you want SMB security, go enable and configure it
by default windows does share out some files and folders, you don’t want that to happen you need to turn them off
you still want to share, but with additional security, you must enable password protected sharing and configure it
if that’s not enough configure samba LANMAN auth and host file entries
and if that’s still not enough you can enable and manage enterprise level security in samba via ACL list
but nobody is going to do it for you
so I’ve also just re-read each of your post above
my only conclusion is that you are completely lost in your understanding of the differences between SMB and DNLA
you have enough info in those post that I can tell they are completely unrelated issues, and the fact that you keep trying to force them to be considered as one issue, just further indicates that you really don’t know how your network is configured for SMB or for DNLA or what the differences are
ok, I’m done, no more help from me
