When debugging in Visual Studio I get message 'Access is denied' in the browser with Local IIS Server NOT with IIS EXPRESS

Question

I am working on an ASP.NET MVC 5 solution right now. When I press F5 (Start Debugging) in Visual Studio 2012, Internet Explorer is opening and I can see Access is denied. (see below) in the tab title. After a few seconds, I access to the first page as intended.

In Visual Studio: If I switch from IE to GC (dropdown choice) and start debugging, I don't get this message.

Any idea why I got this message?

UPDATE: I noticed that

• when checking Use IIS EXPRESS the problem disappear.

• when unchecking Use IIS EXPRESS (so using IIS Web Server) the problem is here again.

Maybe an authorization right?

Answer 1

这可能是由于记录的Internet Explorer错误导致的， 该错误的出现是因为ASP.NET工作进程没有身份验证后模拟客户端的用户权限。

Answer 2

After trying a lot of things as suggested in others posts, finally I had to delete temporary Internet Explorer files. As simple as that.
