When accessing SMB shared that are password-protected, smbclient works just fine.
But when I'm trying to access shared that have no password protection (public shares), smbclient prints:
tree connect failed: NT_STATUS_ACCESS_DENIED
How can I access those shares?
I'm trying to access Windows 7 from my Ubuntu 12.10
