Windows 10 Enterprise with DirectAccess

The following client operating systems support DirectAccess:

  • Windows 10 Enterprise
  • Windows 8 and 8.1 Enterprise
  • Windows 7 Ultimate
  • Windows 7 Enterprise

Here we recommend Windows 10 Enterprise as DirectAccess Client. Because Windows 10 supports automatic entry point selection and transparent failover, better scalability and performance. Also, windows 10 built-in DirectAccess connectivity status indicator, the administrators don’t have to deploy, manage, and maintain additional software.

  1. Login Windows 10.
  2. Press Window Key + I
  3. Click Network & Internet and then click the DirectAccesstab.
  4. Review and configure the settings.


Please make sure the Network Connectivity Assistant service (NcaSvc) is starting if DirectAccess does not appear in the Network & Internet settings window in the user interface.
