HTTP Error 401 - Unauthorized: Access is denied due to invalid credentials. This behavior occurs if the following conditions are true: The Web site that you try to view uses Integrated Windows authentication. The application pool for the Web site recycles during the authentication process.
nice one zain, thank you for that your wonderful and resourceful answer to it. i have gained from your post. well done.
The 401 Unauthorized error is an HTTP status code that means the page you were trying to access can not be loaded until you first log on with a valid user ID and password.
If you have just logged on and received the 401 Unauthorized error, it means that the credentials you entered were invalid for some reason.
Hi Hema, a 401 Error means: Unauthorized: Access is denied due to invalid credentials. This usually happens when you try to visit a site that uses Integrated Windows authentication. To fix this error or at least to receive this error less you should configure application pool recycling. I am sure this will help you in your problem!
