Thank you for your post.
Your system should not need three attempts to launch FileMaker Server. Do you have any other software running on the server? Do you have any virus protection software running on the server? If you do, temporarily turn them off and then restart the server. If you still run into difficulty, try reinstalling FileMaker Server from scratch. If this still fails, then contact our Technical Support department as they will walk through the installation process to make sure you get up and running. If you are located in North America, call toll-free 800-325-2747. If outside North America, contact the FileMaker office nearest you.
