Hi all,
I found out an issue with the code of web.config given by default with Joomla! 1.7 because all components, including CB, were facing 404 error pages.
Microsoft published a solution here, if you need it:
learn.iis.net/page.aspx/527/install-joomla-on-iis/
Copy of code that works just fine:
<?xml version="1.0" encoding="UTF-8"?>
<configuration>
<system.webServer>
<rewrite>
<rules>
<rule name="Security Rule" stopProcessing="true">
<match url="^(.*)$" ignoreCase="false" />
<conditions logicalGrouping="MatchAny">
<add input="{QUERY_STRING}" pattern="mosConfig_[a-zA-Z_]{1,21}(
\%3D)" ignoreCase="false" />
