DirectAccess has been with us for quite some time know, having been originally introduced with Windows Server 2008 R2, later enhanced with Forefront Unified Access Gateway (UAG) 2010, and finally integrated in to the base operating system in Windows Server 2012 R2. Client support for DirectAccess begins with Windows 7 (Enterprise or Ultimate), and also includes Windows 8.x (Enterprise) and Windows 10 (Enterprise or Education).
Although Windows 7 clients are supported for DirectAccess, Windows 10 is highly preferred. Here are three important things you need to know about using Windows 10 with DirectAccess.
- Windows 10 Provides Improved Performance and Scalability – Windows 10 includes support for null encryption when using the IP-HTTPS IPv6 transition protocol. This eliminates the needless double-encryption performed by Windows 7 clients, and dramatically reduces the protocol overhead for clients connecting behind port-restricted firewalls. DirectAccess servers can support many more concurrent IP-HTTPS sessions with Windows 10, and it has the added benefit of making the more secure perimeter/DMZ deployment behind an edge security device performing NAT much more attractive.
- Windows 10 Supports Geographic Redundancy – Windows 10 includes full support for DirectAccess multisite deployments. Where Windows 7 clients had to be assigned to a single entry point, Windows 10 clients are aware of all entry points in the organization. They are able to automatically select the nearest entry point on startup, and transparently failover to another site if the current site becomes unavailable.
- Windows 10 Features an Enhanced Management Experience – From a troubleshooting and support perspective, Windows 10 makes things much easier. The DirectAccess connectivity assistant, an optional component for Windows 7, is now fully integrated with the Windows 10 UI. PowerShell is greatly improved and now includes many native DirectAccess configuration and troubleshooting commands.
As you can see, there are a number of significant advantages for using Windows 10 with DirectAccess. Windows 10 now supports all of the enterprise features of DirectAccess, including geographic redundancy and performance and scalability improvements. Windows 10 is also easier to troubleshoot and manage. If you’re still supporting Windows 7, DirectAccess in Windows Server 2012 R2 can certainly support them. However, without a doubt the best experience, both from an administrator’s and the end user’s perspective, is with Windows 10. Just one more reason to begin planning your migration to Windows 10 with DirectAccess today!
