Event ID 404 — RD Gateway Server Configuration

  • Article

Applies To: Windows Server 2008 R2

For remote clients to successfully connect to internal network resources (computers) through a Remote Desktop Gateway (RD Gateway) server, the RD Gateway server must be configured correctly. The RD Gateway server must be configured to use an appropriate Secure Sockets Layer (SSL)-compatible X.509 certificate, and authorization policy settings must be configured correctly. Remote Desktop connection authorization policies (RD CAPs) specify who can connect to the RD Gateway server. Remote Desktop resource authorization policies (RD RAPs) specify the internal network resources that clients can connect to through an RD Gateway server.

Resolve

Restart the Remote Desktop Gateway service

Remote Desktop Gateway registers an Active Directory Domain Services service connection point each time the Remote Desktop Gateway service is started.

Note: Restarting the Remote Desktop Gateway service also restarts all dependent services.

To perform this procedure, you must have membership in the local Administrators group, or you must have been delegated the appropriate authority.

To restart the Remote Desktop Gateway service:

  1. On the RD Gateway server, click Start, point to Administrative Tools, and then click Services. In the Name column of the Services snap-in, right-click Remote Desktop Gateway, and then click Restart.
  2. If the attempt to restart only the service fails, restart the computer. This forces all related and dependent services to restart.
  3. If you want the service to always start automatically after the server is restarted, in the Name column of the Services snap-in, right-click Remote Desktop Gateway, click Properties, and in Startup type, select Automatic, and then click OK.

Verify

To verify that the RD Gateway server is configured correctly, examine Event Viewer logs and search for the following event messages. These event messages indicate that the Remote Desktop Gateway service is running, and that clients are successfully connecting to internal network resources through the RD Gateway server.

To perform this procedure, you do not need to have membership in the local Administrators group. Therefore, as a security best practice, consider performing this task as a user without administrative credentials.

To verify that the RD Gateway server is configured correctly:

  1. On the RD Gateway server, click Start, point to Administrative Tools, and then click Event Viewer.
  2. In the Event Viewer console tree, navigate to Application and Services Logs\Microsoft\Windows\TerminalServices-Gateway, and then search for the following events:
    • Event ID 101, Source TerminalServices-Gateway: This event indicates that the Remote Desktop Gateway service is running.
    • Event ID 200, Source TerminalServices-Gateway: This event indicates that the client is connected to the RD Gateway server.
    • Event ID 302, Source TerminalServices-Gateway: This event indicates that the client is connected to an internal network resource through the RD Gateway server.
