Verify that a specific event (ID 674) was generated on the federation server proxy computer. This event is generated when the federation server proxy is able to successfully communicate with the Federation Service.

To perform this procedure, you must be a member of the local Administrators group, or you must have been delegated the appropriate authority.

  1. Log on to a client computer with Internet access.

  2. Open a browser window, and then type the Uniform Resource Locator (URL) for the Federation Service endpoint, along with the path to the clientlogon.aspx page that is stored on the federation server proxy.

  3. Press ENTER.

    Note   At this point your browser should display the error Server Error in '/adfs' Application. This step is necessary to generate event message 674 to verify that the clientlogon.aspx page is being loaded properly by Internet Information Services (IIS).

  4. Log on to the federation server proxy.

  5. Click Start, point to Administrative Tools, and then click Event Viewer.

  6. In the details pane, double-click Application.

  7. In the Event column, look for event ID 674.

If the federation server proxy is configured properly, you see a new event in the Application log of Event Viewer, with the event ID 674. This event verifies that the federation server proxy was able to communicate successfully with the Federation Service.
