Web API 2 returns 401 when hosted on IIS and return 200 when set authentication to anonymous

Question

I have a WebApi project , which returns some data , this works fine when we query through the URL , but returns 401 when i invoke it from my console app. this project has been hosted in IIS 8 and i need this to run under windows authentication. If i set it to anonymous authentication then works fine, but gives error to windows auth mode. Thanks in advance.

make sure you have added <authentication mode="Windows" /> under system.web of your application's app.config — Ajay B L

Check HTTP Status Codes RFC ...401 stands for Unauthorized Access means while invoking from your console app you are not passing the Authorization header in your API request.
