Problem connecting with WCF service

Question

Background:

I have a WCF service deployed on my local machine that in turns connects to the SQL Server 2005 database.

To consume the service, I have a client application that dynamically creates the service client to consume the methods exposed in wcf service.

Configuration:

OS: Windows XP
IIS : 5.1

Problem

When I run client FIRST TIME on the local machine ( where service is deployed) it fails to connect with the service.

While debugging I notice when I call any method (exposed in the service) the following error occurred (I have pasted the exception at the bottom).

Now When I go into explorer and type the address to open in the browser like:

https:\\localhost\\TestService\\TestService.svc.

it opens successfully in browser..

Now I again go the client app and try consuming the web service, it connects successfully..

Strange enough, when I re-start IIS, the problem again occurs... To run the client app for the first time, I have to browse it in Internet Explorer.

Note: I have implemented SSL through a certificate..

Exception occured:

The content type text/html of the response message does not match the content type of the binding (application/soap+xml; charset=utf-8). If using a custom encoder, be sure that the IsContentTypeSupported method is implemented properly. The first 163 bytes of the response were: 'ErrorEither a required impersonation level was not provided, or the provided impersonation level is invalid.

The same thing works fine in Windows 2003 server and IIS 6.0

Answer 1

Seem to have good explanation of your problem here.

You should try his workaround by enabling anonymous access on IIS.

Hope this helps...
