I have three machines - two with Windows 7 and one with Ubuntu version 12.4. They are in the same network connected by modem. The two Windows machines share files with no problem, but they cannot see the machine with Ubuntu. On the other hand, I am able to see the shared files of the Windows machines from the Ubuntu machine. But when I select a folder, it asks for the network password. I changed it several times in order to be sure that I am entering the correct one but in every case it says that the password is wrong.
I have read some topics about files sharing between Linux and Windows in which it is said that I should use Samba, but is there an easier way to do this, using the build it options?
