You need to provide a FULL and CLEAR explanation of the problem, which includes exactly what you're trying to achieve, exactly how you're trying to achieve it and exactly what happens when you try. You have partly provided the third of those and nothing else.

Also, the title of the thread should not be an error message. It should be a concise summary of the problem, e.g. "Exception Thrown When Connecting To Database Over Network".

Well, by default, when there is an unhandled exception, an application will crash. So if the question is how to stop it from crashing, then handle the exception somehow. If the question is how to prevent the connection from getting disconnected, then that's another matter entirely and may actually require beefing up your network.
