Problems in an environment will always occur whether it s a server not starting correctly, a server not performing as expected, or other general errors that need to be diagnosed and resolved Fortunately, many troubleshooting tools are available Each chapter looks at troubleshooting each technology being discussed This chapter deals with more generic troubleshooting tools that apply to the entire system Before we go any further, let s cover some basics regarding the units that an operating system (OS) uses for execution and general functionality The following are discussed repeatedly in this chapter:

A process is a container that executes an instance of a program Each process has a unique process ID to identify the process The process will run an executable program, which de nes code to execute and data to be used A process also comprises a private virtual address space This space is the memory that the process uses, which is mapped to physical and virtual memory by the OS This private virtual address space enables each process to have its own memory space without seeing the actual physical memory Thus, it protects the memory content of one process being seen by another process, which is important from both a security and integrity perspective An access token is linked to a process This token de nes the user, security groups, and privileges for the process Each process also has a list of handles that hook into resources that a process uses (such as

a le) and hook into internal OS objects (such as a semaphore) Finally, each process has at least one thread that executes A thread schedules execution of instructions by the OS A process can have more than one thread that share the processes resources, such as the private virtual address space When a program uses multiple threads, it is considered multi-threaded, and this is one way a program can avoid becoming unresponsive while performing activity A process can have one thread handling the user interface elements and another thread performing computations; even if the process is busy working, it is still responsive because it has a thread dedicated to the interface communication Threads are also key to exploiting a multi-CPU (or even a multi-core single CPU) machine A single-threaded application can execute only on one core at a time, whereas a multi-threaded app can execute each thread on a separate core or CPU A job allows a group of processes to be managed as a single unit This is necessary when a task requires multiple processes to function A handle accesses objects When an object, such as a le or database, is created or opened, a handle is returned that is used for access User processes always use handles to access objects Processes keep track of handles, so handles can be useful to see what objects a process is using

In the next section, we look at Recovery Environment (RE), which might be the solution in the event of a problem However, before you try to repair an environment, you have other options The OS Loader for Windows Server 2008 has an advanced boot menu The boot menu gives numerous boot options that can be useful to a troublesome system These options are essentially unchanged from earlier versions of the OS, so if you are familiar with 2003, the 2008 advanced options should be familiar And, in many cases, it will help you resolve a problem before you need to use RE, which requires a more hands-on approach that might make your situation worse

To access the boot menu, rst hit F8 at the Windows Boot Manager screen when you select the OS to boot If you have only one OS con gured, the boot menu might not display for any amount of time (because there is no choice to make) After the BIOS stage has completed the system startup, press F8 when the screen goes black Keep pressing every second until the menu appears, as shown in Figure 20-1 If the Windows logo screen is displayed, you missed it and need to restart the computer (If this happens, try pressing F8 more often and earlier after your computer restarts)
