HTTP Error 401.2 - Unauthorized You are not authorized to view this page due to invalid authentication headers
Solution 1
Make sure Anonymous access is enabled on IIS -> Authentication.
But also right click on it, then click on Edit, and choose a domain\username and password. (With access to the physical folder of the application).
Solution 2
Open Project properties by selecting project then go to
View>Properties Windows
and make sure Anonymous Authentication is Enabled
Solution 3
Same thing happen to me this morning, everything was working fine for weeks before. yes guess what. I change my windows PC user account password yesterday night. (how stupid was I)
So easy fix:
IIS -> authentication -> Anonymous authentication -> edit and set the user and new PASSWORD.
Solution 4
I had the same issue, and spent quite a bit of time trying to track down the solution. I had Anonymous Authentication set up at two different levels with two different users. Make sure that you're not overwriting your set up at a lower level.
