Hi, you can try this From IIS, Go to Authentication then check Anonymous Authentication whether it is enabled or not. enable Anonymous Authentication if it is disabled then Edit it. You will get below screen, Select Application pool identity.

The error may come due to less accessible folder and AppPool having less permission.
