IIS 7, rewritemod2 and Drupal

Last time I have been tinkering with a Drupal installation on a Windows system with IIS 7 on it. Drupal 7 will not install when the fixed rewritemod2 for IIS 7 is not installed and informs you about it. Because I do not shutdown a production system easily I opted for Drupal 6.22 which installs without much problems. That 's to say it does not work correctly but you will not notice untill you try to create some contents or install some contributed modules.

Exactly those partial functioning installs drives you crazy and I wasted quite some time on this one. But today I had some maintenance to do on the server so I also installed rewritemod2 from the official IIS-site with the intention to install Drupal 7. But surprise, surprise after the install Drupal 6.22 now also works as supposed to.
