Ever use NetMon? If you haven't it is worth a look as it is a good tool for performing network monitoring. You can install it from Add/Remove Programs, Add Windows Components, Management and Monitoring Tools. If you have used it you know that, even though it is a great tool, it is a little out of date.
Well NetMon 3.0 is now in beta and offers intelligent filtering, real-time capture and display, a completely new UI, and much more.
