In my smb.conf [global] section I have: hosts allow = localhost mammut eiche hostname lookups = yes This worked with samba 4.13 without errors. After update to samba 4.16 file shares work as before but shared printers are not accessible any more. spoolss log says Denied connection from 10.0.0.69 (10.0.0.69) If I change smb.conf to hosts allow = 127.0.0.1 10.0.0.64 10.0.0.69 Printer shares are working again.
