Locate your Web Service URL
The Starfish ETL Web Service URL is typically http://localhost/StarfishEngine/StarfishService.asmx
If that doesn't work you can find it manually in the IIS Manager (Control Panel > Administrative Tools > Internet Information Services Manager). Browse your available sites on the left sidebar. Look for StarfishEngine and click on it. Then along the right side click Browse and that will take you to the URL.
