This can cause problems when trying to authenticate and on their Windows identity. In this article, we will explore the possible causes of this issue and provide solutions with .

Possible Causes

There are several reasons why the Windows identity may appear as anonymous in the ASP.NET request pipeline. Let's discuss some of the common causes:
