Problem accessing .NET web service from Windows app

I have an AJAX web application. ASP pages are accessing various Web Services that are part of the application using standard Microsoft .NET AJAX extension APIs.

Now, I have to call some of the web services from the Windows app.

It works when I add web reference to a project on my local development machine.

But when I try to access web service from production, I always get redirected to a login page.

I am using Windows XP and IIS5.1 in development and Windows 7/IIS 7 in production.

this is the line from Web.config:

        <authentication mode="Forms">

              <forms name=".localCookies" loginUrl="Login.aspx" protection="All" timeout="60" path="/"/>

        </authenticat开发者_如何转开发ion>

I've tried to set mode to "None" but now I am getting windows authentication screen.

Any idea how to change configurations?

If you can get away with no security on your web services (e.g. Internal Only Server), then change your site's security settings to allow anonymous access to your web service.

<!-- Put beneath the closing </system.web> tag -->
<location path="YourWebService.ASMX" >
  <system.web>
    <authorization>
      <allow users="?" />
    </authorization>
  </system.web>
</location>
