SYMPTOMS

Consider the following scenario:
  • You install the Remote Desktop Gateway (RD Gateway) service on a computer that is running Windows Server 2008 R2.
  • There are multiple certificate bindings on the port 443 of this computer.
In this scenario, the RD Gateway may not work correctly. The incorrect behavior depends on the certificate store name of the selected certificate binding. The following two values of the certificate store name for the binding causes different issues:
  • Certificate store name is not NULL for the binding

    In this case, all connections go through except in the following scenarios:
    • Smart card authentication is configured on the RD Gateway-side.
    • Network Access Protection health checks are enforced on the client-side.
  • Certificate store name is NULL for the binding

    In this case, all connections fail together, and you receive the following error message:
    Your computer can't connect to the remote computer because no certificate was configured to use at the Remote Desktop Gateway server. Contact your network administrator for assistance.
    At the same time, the following TerminalServices-Gateway event that has the ID 306 is added to the TerminalServices-Gateway log:

    Source: Terminalservices-gateway
    ID: 306
    Level: Error
    Description: The user <user name>, on client computer <client computer>, was not authorized to connect to the RD Gateway server because a tunnel could not be created. The following authentication method was attempted: <smartcard/password>. The following error occurred: 23022.

    Note To check whether the certificate store name is NULL, follow these steps:
    1. At the command prompt, type the following command, and then press ENTER:
      netsh http show sslcert
    2. Check the value for Certificate Store Name of the first binding that is listening on port 443. A value of (null) indicates that the certificate store name is NULL for that particular binding.

CAUSE

The issues occur because the RD Gateway service retrieves an incorrect certificate binding.
