CIFS is the protocol used under Microsoft Environment. It’s this protocol that is used when you select ‘Network neighborhood’ under Windows.
If you have a MS Windows computer that needs to access your NAS4Free server, it’s the protocol to use. Open the Services/CIFS page and click and select the enable check box on the right hand side.
Leave all other fields as their Default values for the moment, you can tweak things later. Click the Save button.
Now you should create share's on CIFS:Share tab (See pictures below for my example)
