Default "Windows" authentication with disabled anonymous access was the ticket.  Thanks!

<div>
<div class="content wysiwyg-content">
We are designing a .Net web application which will primarily used by employees. &nbsp;We are Windows environment and we would like users who log into the domain not need to subsequently log into the site but instead the site reference the logged in user's AD group affiliation to enforce security.<br />
<br />
Some users external to our LAN will also need to access the application. &nbsp;If they are logged into their non-company PC we would like for them to be prompted for their AD credentials.<br />
<br />
What is the best authentication for this? &nbsp;Also, how can I set my development environment (Visual Studio 2013 Pro) up to emulate this?

Most suitable authentication method for our IIS web application

IIS is Internet Information Services, the web server included with Windows Server operating systems. All current versions are built on a modular architecture; modules can be added or removed individually so that those required for specific functionality are installed. The full installation of IIS includes HTTP, security, content, compression, caching, logging and diagnostics.

Microsoft IIS Web Server

The successor to Active Server Pages, ASP.NET websites utilize the .NET framework to produce dynamic, data and content-driven web applications and services. ASP.NET code can be written using any .NET supported language. As of 2009, ASP.NET can also apply the Model-View-Controller (MVC) pattern to web applications

ASP.NET

The .NET Framework is not specific to any one programming language; rather, it includes a library of functions that allows developers to rapidly build applications. Several supported languages include C#, VB.NET, C++ or ASP.NET.
