Connecting to Report Web Services from a Secure Web Site
In Crystal Reports for Visual Studio, you can publish Crystal Reports as Web services. For information on how to configure Report Web Services, see Publishing and Consuming a Report as a Web Service.
Because Web services are accessed over the Web, you may want to protect Report Web Services from anonymous access.
This section explains how to remove anonymous access from a virtual directory that contains a Report Web Service, and then write code that places the Report Web Service into a RemoteReportProxy class, which can be configured to address NT authentication on the Internet Information Services (IIS) server.
Two kinds of Report Web Services require authentication code: regular Report Web Services and Server Files. For more information about Server Files, see Configuring Server Files in Crystal Services.
