IISreporter 2.0 is now available. Go and download (www.iisreporter.com/dl).
The free standalone version allows you to monitor the connections on your local IIS server. You can install on as many servers / machines you would like. A new IISreporter Command center version will be released in the next 2 weeks.
I have closed the source code, but the older version v1.7 is still available at sourceforge.net (source) or download at iisreporter.com.
The new version of IISreporter.com has been re-written in C# and .NET 2.0. Performance has been increased and new features have been added.
