The underlying operating system structure and the relationship of component parts are fundamental to deploying and managing Windows Server 2003 environments. By understanding the operating system architecture, the system administrator should be in a better position to install, configure, optimize, and troubleshoot Windows Server 2003. This chapter is an architectural overview of Windows Server 2003. After reading it, you should have the following:
An understanding of the operating system's structural layers, subsystems, and managers, including the executive kernel modes and user modes, subsystems, and managers
A working knowledge of Windows Server 2003 process management, including multitasking, the interplay of processes and threads, process viewing, and management tools
A perspective on physical and virtual memory management
A basic understanding of the boot process
A working grasp of the registry's function and structure
An understanding of application dependencies and software compatibility with Windows Server 2003 through the use of its tools
There have been relatively very few underlying architectural changes made from Windows 2000. However, there are a number of enhancements that will have a beneficial impact on administration.
