It's basically saying that it couldn't find the instance you specified in your connection string. One possibility, as specified in the error message, is that the instance is not configured to allow remote connections. Is the database instance on the same machine as the application? Can you connect to the instance using Management Studio?

Perhaps you could answer my questions. I asked them for a reason.
