Disclaimer: This method is not an officially recognised method of network protection and has not, therefore, been rigorously tested or verified. I cannot guarantee that your PC's shared drives will be totally secure from hackers. If network security is a priority for you, then I would recommend installing a firewall on your Windows box or connect to the internet via a secure computer (ie. a Linux box).

This following guide is for people who connect to the internet with their Windows PC, using a modem. If you connect to the internet via a LAN then this is not applicable.

This guide will assume that you have followed all of the instructions for setting up the PC networking, and is therefore concerned with the alterations and additions that will need to be made. NB. All your Internet connections must be installed before setting up the second Dial-Up Adapter.

Alterations:

1) Disabling File and Print Sharing On The Original DUA.

This is the DUA that you will use to connect to the internet.

	a) Open up the Control Panel, and double click on Network. A window labelled Network should appear. b) There should be a list of all installed network components on your computer. Select the entry labelled TCP/IP -> Dial-Up Adapter, and click on the Properties button situated underneath the list.

	c) Ignore the warning message, and in the resulting window called TCP/IP properties click on the Bindings tab. Deselect both of the tick boxes: Client For Microsoft Networks and File and printer sharing for Microsoft Networks. Click on OK. d) You will then be warned by Windows that your have not selected any drivers to bind with, and it will ask if you would select one. Click on the No button. Follow any onscreen instructions.

2) Removing Your Current Serial Network Connection.

	a) On the PC desktop double click on the My Computer icon, and in the resulting window double click on Control Panel. b) Double click on the Dial-Up Networking icon to get the Dial-Up Networking window. c) Highlight the Serial Network icon by right clicking on it, and select Delete on the resulting menu.
