User guest has been assigned to a share (under access control) – still the guests are unable to login to the share.
Windows users are automatically trying to log in with their own local user and password and not with account
guest therefore the login attempt will be rejected.
If the share is mapped with user
guest - no password then the user will be able to log in.
The easiest way is to
enable guest account under
network - domain and workgroup when joining the workgroup or domain. In this case all users that are not known to euroNAS will be treated as guests. In guest is assigned to a certain share this users will be able to log in automatically.
