Always On VPN client configuration settings are typically deployed in the user’s context. However, this presents a unique challenge when sharing a single device with multiple users who have an Always On VPN profile assigned to them. By design, Windows designates only a single user profile on a shared device to be “always on”. When multiple users with assigned Always On VPN profiles share the same machine, it could yield unexpected results.
Auto Trigger Profile
When an Always On VPN profile is provisioned to a user, Windows records information about this profile in the registry. Specifically, the Always On VPN profile’s name and GUID are recorded, as well as the user’s Security Identifier (SID) and the path to the rasphone.pbk file that contains the Always On VPN profile.
Multiple Users
When a new user logs on to a shared device and receives their Always On VPN profile, Windows overwrites this existing data in the registry with the current user’s information. Each time this user logs on, their Always On VPN connection will establish automatically. Any other users with Always On VPN profiles configured on the same shared device will no longer connect automatically after this. The most recently deployed Always On VPN profile will be designated the “always on” profile.
Connect Automatically
In the above scenario, any user with an assigned Always On VPN profile on the shared device can take over the “always on” designation by opening the VPN connection properties and checking the “Connect automatically” check box.
When this happens, this user will now own the “always on” profile, and other users on the shared device will no longer connect automatically.
Workarounds
If multiple users share a single device requiring Always On VPN connectivity, you have a few options.
Intune
If you are deploying Always On VPN client configuration settings using Intune, you must use the Custom device configuration profile template. Specifically, as shown here, you must deploy your XML configuration file using the ./Device/Vendor/MSFT/VPNv2/ OMA-DM URI.
Unfortunately, the native Intune VPN template does not support deploying Always On VPN profiles in the “all users” context.
PowerShell
When using PowerShell, either natively or with SCCM or another software deployment tool, administrators can use my Always On VPN deployment PowerShell script with the -AllUserConnection parameter.
PowerON DPC
When using PowerON Platforms’ Dynamic Profile Configurator (DPC) to deploy Always On VPN client configuration settings using on-premises Active Directory or via Intune, no changes are required. DPC deploys Always On VPN user profiles in the “all users” context by default.
