Disabling File & Printer Sharing on a Single Computer 
If you are only using a single computer (not using a LAN), File & Printer Sharing should be disabled to reduce any potential security risks on your PC. Please use the following instructions to disable File & Printer Sharing:

1. On the desktop, double-click on My Computer.

2. Double-click on Control Panel.

3. Double-click on Network. 

4. From the Configuration tab, click on the File & Print 
    Sharing button.

 

5. Turn off file sharing and print sharing by clicking each 
     box to remove the check marks. 

6. Click on the OK button. 

7. Select the TCP/IP protocol that is pointing to your Ethernet 
    card or USB cable modem.

 

8. Click on the Properties button and click on the Bindings tab.

9. Click to uncheck the boxes next to "Client for Microsoft 
    Networks" and "File and printer sharing for Microsoft 
    Networks". NOTE: If there is more than one listing of 
    TCP/IP, steps 7-9 should be repeated. 

10. Click the OK button twice and restart your computer.

Enabling File & Printer Sharing on a Local Area Network 
If you wish to share files on a Local Area Network (LAN), you should use File & Printer Sharing with NetBEUI. NetBEUI is a safe, non-routable protocol that can be used on a LAN to share files and printers.

1. Ensure that TCP/IP is not bound to File & Printer Sharing as 
    shown in the     previous section. 

2. On the desktop, double-click on My Computer.

3. Double-click on Control Panel. 

4. Double-click on Network. 

5. Click on the Add button. 

6. Select Protocol, then click the Add button.

7. Under Manufacturers, click on Microsoft and then 
    double-click NetBEUI. 

8. Click on the OK button to restart your computer.

**If you do not wish to disable File and Printer Sharing you may install a firewall and block the incoming traffic on port 135
 UDP.
