You can fix this problem either defining the element in the web.config file of the root dir or setting Virtual Directory as APPLICATION in IIS. For doing this with IIS 6.0, you first have to set the the directory in which your site is present as a Virtual Directory and then define this virtual directory as an Application. All physical directories under Inetpub\Wwwroot are not considered applications until the following procedure is used. 1. Open IIS Manager. 2. Expand the Default Web Site node and look for the subdirectory that you want to designate as an application root. 3. Right-click the directory that you want to mark as an application root, and then click Properties. 4. On the Directory tab, in the Application Settings section, click Create. 5. In the Application name text box, type the name of the application, and then click OK. The virtual directory is now an application root.
