SECURE ACCESS INTERNAL NETWORK RESOURCES WITHOUT VPN – DIRECTACCESS PART1

      No Comments on SECURE ACCESS INTERNAL NETWORK RESOURCES WITHOUT VPN – DIRECTACCESS PART1

Our client is looking to methods of remote access. As such we have been engaged to provide a DirectAccess 2016.
DirectAccess provides users with the experience of being seamlessly connected to their intranet any time they have Internet access. When DirectAccess is enabled, requests for intranet resources (such as email servers, shared folders, or intranet websites) are securely directed to the intranet, without the need for users to connect to a VPN. DirectAccess enables increased productivity for a mobile workforce by offering the same connectivity experience both inside and outside of the office. This document also can be used for DirectAccess 2012R2.


Note

Do not attempt to deploy Remote Access on a virtual machine (VM) in Microsoft Azure. Using Remote Access in Microsoft Azure is not supported. You cannot use Remote Access in an Azure VM to deploy VPN, DirectAccess, or any other Remote Access feature in Windows Server 2016 or earlier versions of Windows Server. For more information, see Microsoft server software support for Microsoft Azure virtual machines.
