The setting "restrict anonymous = 2" prevents accessing IPC$ share as guests from Windows (7) hosts. It works when trying to connect from linux hosts. The error message in the samba log then is: guest user (from session setup) not permitted to access this share (IPC$) Also trying the following in smb.conf does not help: [IPC$] guest ok = yes restrict anonymous = 1 What works is to lesser the security settings (from 2 to 1) in the global section: restrict anonymous = 1 Might also be a feature and not a bug ...
