Ubuntu Networking :: Samba Doesn't Share Folders In 10.04?

I have been looking in the forums but I found no solution for my problem.I already configured Samba and I am sharing folders, printers, etc. (Samba, authentification mode = user, guest account = nobody, share the folder give access to them, enable the permission to access, write, etc.) and seems to be working well.I am trying to connect a Windows to my shared folder in Ubuntu. The only problem is that Samba rejects it and doesn't ask for the password. It just drop the users (from Windows and Ubuntu systems) that try to access to my folders.So when it do in a Terminal sudo smbpasswd -a USERNAMEand I type no password, then it works they everybody can access to those shared but when I type any password then it comes back to the same problem that Samba never asks for passwords and rejects the users.

So the solution would be just give no password to share the files, but the other problem is that every time I restart the user session (restarting the computer, logging out, etc.) it just comes back to the same problem that Samba drops the users and doesn't ask for the password. Seems that every time I restart the system just forgets that I set no password.Another thing is that when I set authentication mode = shareThen nothing works. No password, no access just is possible to see it.
