The latest version is 1.0.6.1. Posted on April 7, 2010.
New Feature in 1.0.6.1: http status colorization and tooltip. On some http requests the response will be something other than "OK", such as Not Found (404), Unauthorized (401) or Forbidden (403). These HTTP status messages may indicate that someone is trying to access your server. Not Found and Forbidden will result in a Yellow row, while Unauthorized, which might mean that someone tried to login and failed will be highlighted as red. If you have no idea what I'm talking about, you can just ignore this feature. Note: Just because a row is highlighted doesn't mean it's a hack attempt. For example a request for Favicon.ico is made by most modern browsers by default. On the other hand, the request to "/webhp" looks odd to me, I should investigate it further. Note: When the row is colorized, there is a tooltip on the first column (IP), hopefully this will help folks who are colorblind and will also distinguish between 403 and 405.
Note on 1.0.6.0 & 1.0.6.1: This version disables "Hide Local Network", which didn't really work right before anyway. Previously, that button would only hide 192.168.*.* addresses. There are other valid private net addresses, like 10.*.*.* that it should have hidden and technically even then it should have been called "Hide Private Network". In a future edition it will be back, and it truly will hide the local network using the server's IP address and netmask. I pulled it for not because I wanted to get the fix for the crash out asap as I haven't had the time to revisit the network problem for a couple weeks.
In order to use this add-in, you must have the following minimal set of IIS logs enabled: date, time, cs-uri-stem, cs-username, c-ip. If you have not changed your log settings and have no clue what I'm talking about then it will work fine for you.

Note on IP blocking: The latest release provides the ability to block incoming requests based on the IP where the request originated. You will see in the logs that many people will be trying to scan your server to see what software you run, as they make requests to URLs that do not exist. However, please consider IP address blocking to be an expert feature! Although the software has some safeguards built-in, if you manage to block the IP of your client systems, you can be locked out of your WHS box! Please use caution with this feature.
