This exercise should be performed on a computer compatible with Windows Server 2003 It assumes that the primary hard drive is completely empty If your disk already has partitions configured, you can modify the exercise to match the configuration of your system 1 Configure the computer s BIOS or the disk controller BIOS to boot from CD-ROM If you are not sure how to configure your computer or disk controller to boot from CD-ROM, consult your hardware documentation 2 Insert the Windows Server 2003 installation CD-ROM into the CD-ROM drive and restart the computer 3 If the primary disk is not empty, a message appears prompting you to press any key to boot from CD If you see this message, press any key After the computer starts, a brief message appears explaining that your system configuration is being inspected, and then the Windows Setup screen appears 4.

Job dependency diagrams include information about timelines and dependencies This information makes it easy to determine the order in which tasks execute, as well as which tasks should execute based on the results of previously executed tasks Consider, for example, a typical sequence of events at a research organization that performs many scientific analyses each week The job dependencies can be described as follows Once the results of the scientific analyses are forwarded to clients, the data should be archived by copying it to a special archive table because it is unlikely to be needed again When it is archived, the data should be removed from the analysis table A consistency check should then be performed on the database, and an operator should be notified of the result If the data archiving fails, this failure should be reported, but the consistency check should still be performed.

Verify that the Device Usage option is set to Use This Device (Enable). If it is not, use the drop-down list to select it. (This might solve the problem.) 5. Select Troubleshoot. 6.

If your computer requires special mass storage drivers that are not part of the Windows Server 2003 driver set, press F6 when prompted and provide the appropriate drivers 5 The system prompts you to press F2 to perform an Automated System Recovery (ASR) Automated System Recovery is a new feature in Windows Server 2003 that replaces the Emergency Repair Disk feature of previous versions of Windows, and is described in 13 Do not press F2 at this time Setup will continue Notice that the gray status bar at the bottom of the screen indicates that the com puter is being inspected and that files are loading This is required to start a min imal version of the operating system 6 If you are installing an evaluation version of Windows Server 2003, the Setup Noti fication screen appears informing you of this.

Similarly, if the analysis data is not deleted, the consistency check should still be performed Finally, the results of the database consistency check should be reported under all circumstances Although this example is reasonably straightforward, you might need to read it several times because text is a linear medium that isn t ideal for expressing branching information As the nature of the job that is being planned gets more complex, the text used to describe it becomes more convoluted Luckily, you can represent complex information more simply by using a job dependency diagram like the one shown in Figure 6-2 In job dependency diagrams, items are linked either by success, failure, or completion These same links are used for workflow tasks when creating a custom maintenance plan or a SQL Server Integration Services (SSIS) package in BIDS.

If a computer has several users, any user can download and install updates (although optional updates require that a user supplies administrator credentials). Typically, recommended and important updates download and install automatically at a time when no user is likely to be logged on. Updates apply to the computer and the computer s OS. They are not applied on a per-user basis.

When creating a job dependency diagram, remember to separate each task and then determine links to later tasks based on the success and failure of the previous task In some situations, the workflow should not terminate when a task fails In the previous example, the database consistency check should occur even if earlier tasks had failed Although there is no one correct diagram for a set of tasks, after you have completed a job dependency diagram, the diagram is likely to be good if implementing the job is easier than it would be with only a list of instructions..
