Turn off Simple File Sharing

(This applies to Windows XP Professional only):  Windows XP has 2 modes for sharing. The first is called "Simple File Sharing" and the other is referred to as the "Classic security model". Simple File Sharing allows (actually forces) that users access those shares under the Guest account. As you can surmise this isn't the most secure solution even though the Guest account has limited privileges. The Classic security model forces users to have an account on your computer and to authenticate by using the password associated with that account.

· How to Turn off Simple File Sharing:

Go to Start > Control Panel > Folder Options . In the resulting window, click on the View tab > Under Advanced Settings: scroll all the way to the bottom and uncheck Use simple file sharing (Recommended) , click Apply and OK and close out all the open windows.

· Add Users

Now that we forced users to authenticate themselves, we need to add accounts for them.

· Go to Start > Control Panel > User Accounts > and choose Create a new account > in the resulting screen enter a name for this account and click Next > in the resulting choose Limited account > now click Create Account.

· This takes you back to the User Accounts screen. Click on the account you just created > in the resulting screen choose Create a password > fill in the blanks with the appropriate information.

· VERY IMPORTANT

The user name and password should be EXACTLY the same as the account on the other machines for them to access your shares!

Use the IPX/SPX protocol on your home network

A protocol is a language that computers speak to one another. The main language (protocol) of the Internet is TCP/IP and this is also the language that by default Microsoft networks speak. The problem with this is that computers on the Internet can listen in to the conversations in your home network. This means it can not only overhear your computers talking to one another but can join the conversation.

   For instance: Say you want to share your mp3 folder with the computer in another room. When that folder is shared it will announce to everyone that it is shared and even give directions on how to reach itself. It will make these announcements whenever your computer starts or whenever another computer asks if it is sharing anything.

   To prevent this from happening you can tell your computer to stop speaking TCP/IP for your home network and speak IPX/SPX instead. The advantage of this is that the routers that control the Internet are specifically told NOT to speak IPX/SPX leaving your home network conversations private.

To do this we are going to start from a clean slate (all these steps must be done on all computers in your network!!!):

· Remove all shares. This includes drive, folders, files, and printers.

· Next install IPX/SPX.  From the default type screen:

· Right-click on My Network Places and choose Properties .

· If you do not have a My Network Places in your menu, let's add it now!  Right-click on the Start button and choose Properties . In the resulting screen click the Customize next to Start menu. In the resulting screen click on the Advanced tab up top. In the box that says Start menu items: scroll down until you see My Network Places and put a check mark in the box next to it. Click OK to exit out of the screens.

From the "Classic" type screen:

· Right-click on My Network Places and choose Properties .

· Find your Local Area Connection icon, right-click on it and choose Properties .

· In the resulting screen click the Install button

· In the resulting screen, double-click on Protocol .

· In the resulting screen double-click on NWLink IPX/SPX/NetBIOS Compatible Transport Protocol and click OK .

· Unbind TCP/IP

All connections have a protocol that is part of it. That is referred to as "binding". As configured we still have 2 bindings, TCP/IP and IPX/SPX. We need to remove or unbind TCP/IP from that connection.

· Right-click on My Network Places and choose Properties . At the top of the screen click on Advanced and choose Advanced settings...

· In the resulting screen, uncheck the boxes that say Internet Protocol (TCP/IP) under BOTH File and Printer Sharing for Microsoft Networks and Client for Microsoft Networks.

· Click OK, exit out of all screens and restart your computer. After restart you can re-do your shares.
