We\'ve inherited an application that uses the Intelligencia.UrlRewriter module. Our environment though is IIS7. We\'ve already set our site to run in the classic asp.net app
Yes I had the exact same problem with Intelligencia.UrlRewriter module, running under Win Vista & IIS7, however switching to the classic asp.net app pool did fix the problem. Are you running the app in a new virtual directory? That can sometimes mess with the root path to the application which could make a difference to the rules in the web.config
