Event ID 103 — RD Gateway Server Configuration

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.

Event Details

Resolve

Ensure that the required permissions are granted to the private key of the SSL certificate

To resolve this issue, ensure that required permissions are granted to the private key of the SSL certificate.

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

To grant the required permissions to the private key of the SSL certificate:

1. On the RD Gateway server, open the Certificates snap-in console. If you have not already added the Certificates snap-in console, you can do so by doing the following:
   1. Click Start, click Run, type mmc, and then click OK.
   2. On the File menu, click Add/Remove Snap-in.
   3. In the Add or Remove Snap-ins dialog box, in the Available snap-ins list, click Certificates, and then click Add.
   4. In the Certificates snap-in dialog box, click Computer account, and then click Next.
   5. In the Select Computer dialog box, click Local computer: (the computer this console is running on), and then click Finish.
   6. In the Add or Remove Snap-ins dialog box, click OK.
2. In the Certificates snap-in console, in the console tree, expand Certificates (Local Computer), expand Personal, and then navigate to the SSL certificate for the RD Gateway server.
3. Right-click the certificate, point to All Tasks, and then click Manage Private Keys.
4. In the Permissions for <Name> private keys dialog box, under Group or user names, click NETWORK SERVICE. Under Permissions for NETWORK SERVICE, if Read is not allowed, select the Allow check box adjacent to Read.
5. 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.
