also to connect to it, you use \\ ipaddress of pc connectin to \ shared folder name

Good advice, virtually what I was going to put.

Overview
This package contains the Link Layer Topology Discovery (LLTD) responder. The network map on a computer running Windows Vista shows a graphical view of the computers and devices on your network and how they are connected by using the LLTD protocol. The LLTD responder must be installed on a computer running Windows XP before it can be detected and appear on the network map. After you install this item, you may have to restart your computer.
