The latest build for Netmon is not available for download. I strongly recommend you to download this new version and test it. There are lots of new features that you will be surprise and glad that they were put in place. Also, check out some of the new features in Netmon Team Blog: http://blogs.technet.com/netmon/archive/2008/09/17/network-monitor-3-2-has-arrived.aspx
