To start the Secondary Logon service:
- Bring up the Windows services management window by running
services.msc.
- Find the Secondary Logon service in the list of services and double-click on it to open its settings window.
- In the service's settings window:
- Select "Automatic" in the Startup type field;
- Click Start;
- Click OK.
- Verify that the service started successfully in the window with the list of services (the Status field should say "Started").
