Hi everyone,
I have a situation where Host A (USB smart card reader connected) trying to rdp to Host B, however, Host B was not able to detect the smart card reader on Host A in the remote session.
Thing I have tried:
Host B Specification:
Edition: Windows 10 Enterprise LTSC
Version: 1809
What I wanted to achieve is Host B able to detect the smart card reader connected to Host A in the remote session from Host A to Host B.
I have spent quite sometime for this issue but still not able to find out what is the issue.
Anyone can shed some lights regarding this ?
Thanks in advance

If host A is a Windows Home edition it may not have the Smartcard Minidriver installed. In our experience Windows 10 Professional had this already built in but Windows 10 Home did not.

Try these so I understand where you are?
1) With USB smart card in Host A - type certutil -scinfo * you should get an output
2) With USB smart card in Host A and you are now RDP'ed onto Host B - type certutil -scinfo *do you get an output.
In my own case I do, I have to install the smart card drivers on Host B in a different way as per vendor guidance.
Hi Fred,
Apologize for the late reply.
I have tried what you have mentioned and the following are the output for each mentioned step:
1) The Microsoft Smart Card Resource Manager is running
2) The Microsoft Smart Card Resource Manager is not running, although Smart Card service is running (I have also changed the startup type to Automatic too)
For 2), when I access Host B directly from the machine, the output is "The Microsoft Smart Card Resource Manager is running". However, when I rdp from Host A to Host B, the output become "The Microsoft Smart Card Resource Manager is not running".
Another thing that I have tried, I got another machine, Host C. So I tried from Host A (With USB smart card connected) RDP'ed onto Host C, the smart card on Host A can be detected on Host C. When I typed the command you have given, the output was "The Microsoft Smart Card Resource Manager is running".
Hope this illustrate my issue better.
Again, thank you in advance
Hi there,
Before you create your Remote Desktop session, click on "Show options". Under the "Local Resources" tab there is a "Local devices and resources" panel. Click the "More" button. Click on "Smart Cards". You can't use the locally plugged smartcard of the server you RDP into, as your session is redirected to the client then only the client's smartcard is accessible in the RDP session. Microsoft made it like this for security reasons.
As a part of the Common Criteria compliance, the RDC client must be configurable to use Credential Manager to acquire and save the user's password or smart card PIN. https://learn.microsoft.com/en-us/windows/security/identity-protection/smart-cards/smart-card-and-remote-desktop-services
Hope this resolves your Query!!
