security parameter set to everyone
The problem is that the other users are not "everyone", they are "guest". Your PC has no way (Active Directory) to authenticate those users.
You could enable the guest account and grant it access, but I don't like doing that. That gives access to any user/machine that can get on your network.
What I do on my home network is to create local accounts with the same name and password on all of my machines. I log on to my laptop with my Microsoft account but that maps to a local account. Open a command prompt and run whoami.exe to see your account name.
Do your users log in to the other pc's with a Microsoft account, or a local account that you created?
