3. Solution Overview Situation ● The Microsoft Product Support Services Internet Web site consisted of a single monolithic application, which presented several management and development challenges Solution ● Develop a component-based infrastructure that exposes data through.NET XML Web services that multiple subscribing applications can use, enforcing a common set of business rules for all consumers of the Web service and insulating the infrastructure from UI changes that require no schema or business rule modifications Benefits ● Increased customer satisfaction and faster time to resolution ● Per incident cost savings; 30–35 percent of Windows XP incidents have been submitted over the Web versus over the phone, and each one saves approximately 53% of average minutes per incident compared to over the phone ● Ease of use; The presentation layer is tightly integrated with the Windows XP Help Center, providing seamless internet data access with user desktop computers

4. Products And Technology ● Microsoft.NET Framework Beta 2 ● Visual Studio.NET Beta 2 ● IIS 5.0 ● Windows 2000 SP2 ● Passport version 1.4 ● SQL Server 2000 ● XML data ● Unicode ● ASP + ● C# ● C++

5. Architecture ● eSupport infrastructure built entirely through Visual Studio.NET ● Five developers completed ● Four intranet sites ● Five XML Web services ● Two Windows NT services ● One console application ● One Internet Server Application Programming Interface (ISAPI) filter ● Reusable utilities and class libraries ● Two developers created/converted six Unicode databases ● Two developers handled consolidation of incident, contract, and product data worldwide

6. Deployment ● eSupport project team developed, tested, and implemented infrastructure ● Components were written in C# through.NET-based technologies ● XML Web services return data in standard XML format ● Using.NET makes it possible to easily publish, install, and configure application components on an intranet site ● Lessons Learned ● IIS metadata describing the Web sites for XML Web services and Internet and intranet applications must be stored in the IIS meta-database ● Not all configuration data can be stored in application configuration files

7. Summary ● The integration of Windows XP with the eSupport infrastructure has resulted in more customers using the electronic submission process and a reduction in the amount of time needed to resolve customer issues ● The interoperability provided by the.NET Framework ensured that eSupport infrastructure integrated seamlessly with existing applications, and that security requirements for authentication and authorization were met ● The project’s XML-based approach saved countless hours of troubleshooting problems that never occurred because human error was eliminated from creating, configuring, and installing components of the Internet site
