The first thing you need to do on the computer you want to enable file and/or printer sharing is to check if the sharing service is already installed. Just hit Start, Setting, Network Connections and double click the network card installed on your PC.
On the window that will show up, click on Properties.
On the next screen you should check if “File and Printer Sharing for Microsoft Networks” is enabled, see Figure 3.
If not, you will need to install this service, by clicking on Install, Service, Add, select File and Printer Sharing for Microsoft Networks, then Ok.
With this service installed you will be able to share folders and printers. Note that this service is not required on client computers, i.e., computers that will access the files or printers located on your computer.
