i have 2 problems first; When I connect with windows client, printers and other computers appear on the network page, but my samba folder is not visible, I have to enter with the ip address. I activated SMB1 but nothing changed.

second; When I log in with an IP address, it asks me for a password on the first attempt, and then I can log in without a password. I want it to ask for a password every time I log in. I made the gpedit.msc settings, but the situation is still the same, I enter the folder with a password, I close the folder, and when I open it again, it enters without asking for a password. How can I fix this situation?
