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!
