Since the book is creating an entire solution step by step each chapter builds upon the next.
The source code is broken out by chapter and each zip file contains the entire solution with 
all the supporting projects.

You should unzip each chapter to a separate folder and create a virtual directory in IIS called
"PaidTimeOffUI" that points to the "ChapterX\PaidTimeOffsolution\PaidTimeOffUI" folder. 
When creating the virtual directory in IIS you must disable Annoymous access to the site and 
enable Integrated Windows authentication.  The web site uses Windows authentication in its 
security model.  Chapter 1 explains how to create the solution using Visual Studio 2008 and these
setting are set automatically for you if you follow the instructions in the book.

Before opening up any solution in Visual Studio you must make sure that the IIS Virtual directory is 
pointing to the appropriate PaidTimeOffUI subfolder for that chapter.

The database script can be found in the "Final DBScript With Data" zip file.  This file contains all the 
tables and stored procedures that are used within the book.  Each table and stored procedure
is defined in the appropriate chapter in the book.  You need to create the database in SQL Server 2005 
and name it HRPaidTimeOff.  Once you have created the database you need to change one record in the 
ENTUserAccount table so the WindowsAccountName field contains your Windows logon.  Chapter 6 explains
how this table is used in the security model.

Enjoy the book!
