Not able to get the Windows User Name using 'User.Identity.Name' in ASP .NET

I am trying to use 'MsgBox(User.Identity.Name)' to show the Current Windows User in a MessageBox. The MessageBox that appears shows "App_Web_1gu0lxe5" as the Title and Message is Empty. In other words I am not able to get the Current Windows User in the Output.

I am using Windows 8.1 Enterprise, 64-bit Operating System, Microsoft Visual Studio 2012, Visual Basic is the Programming Language and I am trying to develop a Web Application.

When I am running the same code on a Machine running "Windows 7 Enterprise, Service Pack 1, 64-bit Operating System" the code produces the desired result.

Any Idea what could be the cause of the Problem?

Did you host the site on IIS? If yes then did you make all the settings proper in IIS to manage the Windows Authentication?

MsgBox is not something that will work in ASP.Net. You need to enable Windows Authentication to be able to get that user name.
