I believe another item I tried was AllowPathInfoForScriptMappings.
You can readup on it HERE
Enabling this will disable any asp pages and some say it is a security risk.
You can access it from the IIS console or in my case I think I had my host change it. By default it is off.
This causes the complete path to be passed to path_info value if off.
You might want to peek at the /forums.bella site and see if the setting is different from the wineintro site.
Also in lieu of testing the friendly urls on the board.
You can create a php file say pathinfo.php and place:
PHP Code

<?php echo $_SERVER['PATH_INFO']; ?>
in the file.
Assuming you have that variable.
Up load it to your site
Then all you do is type say www.winintro.com/pathinfo.php/bella in a browser
If it is working all you should see displayed is /bella
