I'm learning "Beginning ASP.NET 2.0 with C#",ISBN 978-0-470-04258-8.
There's an example of a website "www.wroxunited.net" in the book and I've downloaded the code from the site and saved it as written in the book. I'm using Windows XP Professional with SP3, Visual Studio Enterprise Edition 2005 with SQL Server 2005 Express edition (which comes with the Visual Studio 2005). Now whenever I'm trying to run the example code it's throwing an SQL Exception "Timeout expired. The timeout period elapsed prior to completion of the operation or the server is not responding." Please help me to solve this problem.
The copy of the complete exception is as follows :

System.Data.SqlClient.SqlException was unhandled by user code
  Message="Timeout expired. The timeout period elapsed prior to completion of the operation or the server is not responding."
  Source=".Net SqlClient Data Provider"
