When you first launch the tool, you will be given two options, one to 'Scan your system', and two to 'Set scanning options'. If you choose the first item, the program will start scanning your system right away. If you select the second option, you can configure which tests and network components get scanned (such as: mail, Internet Proxy, etc.)
When the scan completes, a list of different network components and connections will be displayed and whether they passed or failed the diagnostics. If a component fails you can drill down into it to see what is wrong. This tool returns a lot of good technical information, and may not be too understandable to for someone doesn't understand what they're reading.
