Always On VPN RasMan Device Tunnel Failure

Always On VPN RasMan Device Tunnel FailureAn Always On VPN device tunnel is an optional configuration for Windows 10 Enterprise edition clients designed to provide machine-level remote network connectivity. This capability provides feature parity with DirectAccess for domain-joined clients to support scenarios such as logging on without cached credentials and unattended remote support, among others.

Device Tunnel Failure

When configuring a Windows 10 client to use an Always On VPN device tunnel, you may find that the device tunnel works without issue after initial deployment but fails to connect after the computer restarts. In addition, the Windows event log will include an Event ID: 1000 application error with the following error message:

Faulting application name: svchost.exe_RasMan

Always On VPN RasMan Device Tunnel Failure

Known Issue

This can occur when a Windows 10 machine is configured with a device tunnel only (no user tunnel). This is a known issue with Windows 10 v1709. It has been resolved in Windows 10 v1803 (RS4).
