Windows 11 RDP No Smartcard Credentials Shown

Question

When attempting to use RDP to connect to another local desktop, after entering the name of the computer and hitting "connect" it prompts for credentials, however there are no credentials shown. A smart card is used to login to the computer and the credentials on the smart card are able to be seen and used when signing documents or logging into other websites and applications, so the problem seems to be exclusive to RDP. The credentials show and work fine using RDP on older desktop / laptop models we have and the problem seems to have recently appeared as it worked fine some days ago.

Answer 1

Hi, does a root certificate or some work got done into the network ? as please see that document, as it seem your rdp client try to signin with the smartcard certificate. https://learn.microsoft.com/en-us/windows/security/identity-protection/smart-cards/smart-card-and-remote-desktop-services ,

You could show us the windows it show to you when it connect, as usually it should display the certificate, and your user can select other below it to enter their credential.

Lastly, a dirty tip, if you deploy the .rdp file is to force the login inside it. try enablecredsspsupport:i:0 and/or redirectsmartcards:i:0 (https://learn.microsoft.com/en-us/windows-server/remote/remote-desktop-services/clients/rdp-files)

Answer 2

Hello,

This can be due to several reasons, such as smart card redirection not being enabled, driver issues, or problems with the smart card reader itself.

Here are some steps you can take to troubleshoot the issue:

1. Check Smart Card Redirection: Ensure that the smart card redirection is enabled in your Remote Desktop client settings. This can be done by opening the Remote Desktop Connection client, clicking on "Show Options", going to the "Local Resources" tab, and making sure that the "Smart cards" option is selected under "Local devices and resources".

2. Verify Smart Card Reader on Remote Machine: On the remote machine, open the Device Manager and check if the smart card reader is listed under "Smart card readers". If it's not listed, you may need to install the smart card reader driver on the remote machine.

3. Update or Reinstall Smart Card Drivers: If the smart card reader is not being recognized, consider updating or reinstalling the drivers for the smart card reader on both the local and remote machines.
4. Test the Smart Card Reader Locally: To rule out any issues with the smart card reader itself, test it on another machine to see if it's working properly.
5. Check for Service Issues: Make sure that the Smart Card service is running on both the local and remote machines. You can check this by running services.msc and looking for the Smart Card service.
