On a Windows Vista-based computer, you use a smart card to log on to a Windows Server 2003 Terminal Server through a Remote Desktop Protocol (RDP) session. Then, you remove the smart card. In this scenario, you may receive the following message in the remote RDP session:
The card supplied was not recognized. Please check that the card is inserted correctly, and fits tightly.
When the issue occurs, the RDP session is locked as expected.
This problem occurs if the Interactive logon: Smart card removal behavior Group Policy setting is set to Lock Workstation, and this setting is applied to the Terminal Server.
This problem only occurs on a Windows Server 2003 Terminal Server.
This problem does not harm the computer. You can safely ignore this message.
