Can you post your /etc/samba/smb.conf and /etc/dnsmasq.d/dhcp.conf?
From notes I have from a while ago:
I've had another test today.I don't know if this helps.
1 - Without the SMB1.0 client enabled in Win10, with a domain logon, my server never shows in the Network tab.
2 - With the SMB1.0 client enabled in Win10, with a domain logon my server always shows immediately in the Network tab. I can then click on the server icon and see its shares.
Restricting Samba to SMB1/NT1 is irrelevant.
