After the federation proxy service has been configured, use the following procedure to verify that the service is operational:
1. Log on to the federation server proxy system using an account with local administrator rights.
2. Open the Event Viewer; then, under Applications and Service Logs, expand AD FS 2.0 Eventing, and click on Admin.
3. In the Event ID column, search for an event with ID 198. If event ID 198 is shown, this indicates that the federation server proxy service was started successfully and is now online.
