Ditto -- and I want password protected sharing on. I want only people who have accounts to access the drives. We often have guests in our home and I don't want them accessing the shared directories.

Already found this (and several more like it) -- there is no longer a home group in windows 10. Yes, I can ping PLEX from PYRITE and vice versa. Yes, I can access a computer with IP, just NOT name. Verified all the discovery/settings are correct. Yes, all the services are there and running.
This is a rehash of everything above.
Ditto.

It doesn't help to give a long list of links to the same things over and over again.
I'm pretty certain the problem is more network related and most likely to one specific computer, PYRITE.
As I said, PYRITE can not see itself on the network and it should be able to. And I think that's the reason it can not connect to the other computers. If it were able to connect to the others, then maybe the read/write permissions would be correct.
The errors I reported originally have not changed.
Please review my original post and particular the pictures I sent.
Thank you.
