Files on laptop are accessible overnetwork without logging on.
I have discovered by accident that I am able to access the shared files on my
laptop PC from my desktop PC over a local wireless network even when I have not logged on to the laptop. This behavior is seen when running two different applications on my desktop for backing up files to the laptop and comparing files and folders between the laptop and desktop machines. I'm wondering if this represents a security hole in Windows XP Professional SP-3 or a secure feature of networking. I run Windows XP Pro SP-3 on both machines. |

Since you have XP Pro on both machines, the important detail left out is whether you are using "Simple File Sharing" or not. When connecting to any other computer, you must authenticate to it. With Simple File Sharing enabled (default), all connections are forced through the "Guest" account and individual permissions are non- existant. XP _Home_ forces Simple File Sharing to be enabled. With Simple File Sharing disabled, then you must authenticate based on username and password. By default, the username and password of the user on the connecting machine is attempted on the target machine. If you have the same username and password on both machines, then you will automatically be authenticated without challenge. If the same usernames exist on both machines but the passwords are different, connection is denied. Otherwise, it will ask for username and password to connect.
