70-742 Additional Notes – The Remote Access Server Role and WAP


The important Remote Access server role incorporates the following technologies:

  • Remote Access Service (RAS)
  • Routing
  • Web Application Proxy (WAP) 

The Web Application Proxy is the most relevant role service above for the 70-742 exam and it explicitly makes the exam blueprint.

Remember the Web Application Proxy is to provide reverse proxy functionality for Web applications that exist inside your corporate network. What this means is that it permits outside users (on any device) to access these Web applications from outside your network.

WAP pre-authenticates access to your Web applications using Active Directory Federation Services (AD FS) and can also function as an AD FS proxy.

To install this powerful service, use the Add Roles wizard and target the RAS server role – or use PowerShell as follows:

Install-RemoteAccess -VpnType SstpProxy

Some features of WAP that are new in Server 2016 include:

  • Preauthentication for HTTP Basic application publishing – this allows mobile devices to use ActiveSync with Exchange
  • Wildcard domain publishing of applications  – this simplifies integration of services like SharePoint that have many applications in a domain to be published
  • HTTP to HTTPS Redirection
  • HTTP application publishing using pass-through preauthentication
  • Remote Desktop Gateway Apps
  • Better debug logging
  • Admin Console UI improvements
  • Propagation of client IP address to backend applications
