In case that the solution doesn't work, you have to enable Windows Authentication in iss manager. How to do that:

1.To start IIS Manager from the Run dialog box: On the Start menu, click All Programs, click Accessories, and then click Run. In the Open box, type inetmgr and then click OK.

2.In the Connections pane, expand the server name, expand Sites, and go to the level in the hierarchy pane that you want to configure, and then click the Web site or Web application. 3. Scroll to the IIS section in the Home pane, and then double-click Authentication.

4.In the Authentication pane, select Anonymous Authentication, and then click Disable.

5. In the Authentication pane, select Windows Authentication, and then click Enable.

I struggled with this problem the past few days.

I suggest reading Scott Guthrie's blog post Recipe: Enabling Windows Authentication within an Intranet ASP.NET Web application

For me the problem was that although I had Windows Authentication enabled in IIS and I had <authentication mode="Windows" /> in the <system.web> section of web.config, I was not preventing anonymous access. This last part was the key. You need to prevent anonymous access to ensure that the browser sends the credentials.

You can either configure IIS in Control Panel so that your site (or machine) uses Windows authentication and denies anonymous access or you can add the following to your web.config in the system.web section:

<authentication mode="Windows" />

<authorization>
   <deny users="?"/>
</authorization>

Disabling all other options in authentication tab of iis except windows authentication resolved my issue. Please check..

Steps:

1. Open iis in your machine
2. Select your application from the application pool
3. Click on authentication option
4. Disable all other option except windows authentication (Anonimous authentication should be disabled)

Please check this and let me know the feedback. It worked for me. hope it will work for you also..

Answer 4

These might resolve the issue(It did for me). In IIS Express change the project property values, "Anonymous Authentication" and "Windows Authentication". To do this, when project is selected, press F4 and then change these properties.

In case you are deploying it on IIS locally, make sure local machines "Windows Authentication" feature is enabled and "Anonymous Authentication" is disabled.

Answer 5

As @PaulTheCyclist says, If using IISExpress anonymous authentication is enabled by default, windows authentication is disabled.

This can be changed in what I'm sure used to be called PropertyPages (NOT right-click -> properties). Select the web project

Answer 6

Apart from all obvious reasons mentioned earlier, there might be another one: you didn't put an Authorize attribute on top of your controller, like that:

[Authorize(Roles = "myRole")]
[EnableCors(origins: "http://localhost:8080", headers: "*", methods: "*", SupportsCredentials = true)]
public class MyController : ApiController

At least that's what worked for me.
