I have a ASP.NET web application that makes use of Windows Authentication. However, I have a particular folder that I need for anyone to be able to call ( anonymous ) The application is running on Windows 2008 Server. I have Set the authentication of the folder were the web service resides to anonymous, yet I still get prompted for my windows credentials. If I hit cancel ( not providing anything ) the web service still works as expected. I need for a linux system to be able to access the web service.
