Hi pals,

I have a WCf service to handle file upload. I have enabled the transfer mode as streamed to send large file of data. I ma bale to achieve till 300 mb.

Now i need to provide the security for my service. I have implemented the ntlm authentication for my service. When i hosted it on IIS and enabled the Integrated windows authentication in iis and browsed the endpoint. I am receiving the following error.

HTTP request streaming cannot be used in conjunction with HTTP authentication.  Either disable request streaming or specify anonymous HTTP authentication.
Parameter name: bindingElement

How can i overcome this problem? Can i use windows authentication on streamed mode? Else which authentication will be suitable for streamed mode? Can anyone pls help me on this?
