If, like me, you are using RDP (Remote Desktop) during testing and would like to try this from a computer that is not part of the domain where the Smart Cards are to be tested, you are likely to hit some problems:
The RDP server needs to have Allow connections from computers running any version of Remote Desktop (less secure).
If you get the error This computer can't connect to the remote computer because the smartcard credentials are not available..., you might need to import the certificate (not the private key, just the certificate) from the Smart Card, into your certificate storage.
