AlwaysOn VPN certificate with Smart Card Logon EKU returns Smart Card Resource Manager error

When connecting to an AlwaysOn VPN user tunnel, some devices return the following error: "The Smart Card Resource Manager is not running."
Starting the "Smart Card" service manually does not resolve the issue, and also is not a sustainable solution even if it did. The required certificate is present in the user's Personal store.

A quick registry keys comparison between a working device and a device returning the error does not reveal any differences in service configuration . Some devices do seem to resolve this issue by themselves over time. Some do not.

The devices have previously been controlled by GPO (they are now being managed by Intune) so there may be some left-overs, but you would think this would in that case not be an intermittent issue, but estate-wide.

I'm looking for any insight, advanced troubleshooting steps, or a straight up solution if anyone has one.

Thanks for reading!

    Hi,

    Thanks for your update.

    Have you try to uninstall and reinstall the smart card manager to see if the issue still exist.

    If the issue till existed, we need collect some necessary traces to figure out why the service was stopped. If your issue is urgent, I would suggest you open a case with Microsoft where more in-depth investigation can be done so that you would get a more satisfying explanation and solution to this issue.

    Also, in this way ,they can have a clear picture about your issue and your environment by phone communication and live share session.

    You may find phone number for your region accordingly from the link below:
