Active Directory Logical Structure

Active Directory Logical Structure In Windows 2000, a domain defines an administrative boundary for a collection of objects that are relevant to a specific group of users on a network. A domain is an administrative boundary because administrative privileges do not extend to other domains and because each domain has a security policy that extends to all security accounts within the domain. Active Directory stores information about objects in one or more domains. Domains can be organized into parent-child relationships to form a hierarchy. A parent domain is the domain directly superior in the hierarchy to one or more subordinate, or child, domains. A child domain also can be the parent of one or more child domains, as shown in Figure 1.1. Figure 1.1 Example of a Domain Hierarchy This hierarchical structure is a change from the flat domain structure of Microsoft® Windows NT® version 4.0 and Microsoft® Windows NT® version 3.51. The domain hierarchy of Windows 2000 allows you to search mul

Windows XP Boot Sequence

WINDOWS XP BOOT SEQUENCE As with other Windows Operating Systems, when you turn on your PC, it goes through an elaborate boot up process. It begins when the computer performs the POST (power-on self test), followed by the POST for each adapter card that has a BIOS, for example, your video card. The BIOS then reads the MBR (Master Boot Record) which is in the first sector of the first hard disk and transfers control to the code in the MBR which is created by the XP Setup. This is where Windows takes over the startup process. What comes next? Here's what happens: 1. The MBR reads the boot sector which is the first sector of the active partition.This sector contains the code that starts Ntldr which is the boot strap loader for Windows XP. The first role of Ntldr is to allow full memory addressing, start the file system, read boot.ini and put up the boot menu. IMPORTANT: Ntldr must be located in root folder of the active partition along with Ntdetect.com, boot.ini, bootsect.dos (f

Clusters

Chapter 1: Understanding Clusters and Your Needs 1.1 Writing a Request for Proposal (RFP) for a cluster that will succeed Picture yourself in the early 1980s. You are assigned the task of designing a new computing system. Your guidelines are slim at best. The situation can only be described as: "I don't know what I want, but I will know it when I see it." The only defense against this type of statement is to sit down and write what is called a Request for Proposal. The Request for Proposal would possibly look like: I don't know what I want in a computer system, but it should provide at least the following characteristics: § Availability § Reliability § Scalability The design of the cluster computer system evolved as an answer to such a Request for Proposal. The term "cluster" as it applies to the computer industry was popularized by Digital Computer Corporation in early 1983 with VMS version 3.7. Two VAX 11/750s maintained cluster communication at the rate o
