Chapter 1: Introduction: Migrating from Windows NT 4.0 to Windows 2000Welcome to Windows 2000 and Exam 70-222, which covers the skills necessary for migrating a corporate network from Windows NT 4.0 to Microsoft's new and powerful network operating system. This exam is an important elective for the Windows 2000 Microsoft Certified Systems Engineer (MCSE) certification track because many experienced Windows NT administrators are likely to select it as an "easy" pass, due to their prior knowledge of Windows NT.
Your knowledge of Windows NT networking provides a good foundation for studying for this exam, but, by itself, it's not enough. Although networking fundamentals remain the same at the physical level, administration of a Windows 2000 network requires many skills that were not required of a Windows NT 4.0 administrator. With many new features and a new emphasis on topics that were only touched on lightly in your Windows NT training (such as DNS), Windows 2000 is changing the world of networking and the way administrators perform common tasks.
To understand and troubleshoot the new operating system, you must first have a thorough understanding of basic TCP/IP concepts such as Domain Name System (DNS), the dynamic host configuration protocol (DHCP), and Routing and Remote Access Services (RRAS). Networking is what Microsoft's new operating system-and computing in general-is all about today. Understanding how to build, use, maintain, and troubleshoot the network infrastructure in the new Windows 2000 environment will be necessary to pass the exam.
Another big change in Windows 2000 is Microsoft's new directory service, the Active Directory (AD). Active Directory isthe component around which a Windows 2000 network revolves. Unlike the Windows NT directory service, AD is much more than just a security accounts database. The Active Directory is integrated with the security subsystem, but is used not only to manage security accounts but also to store information about objects such as shared folders, printers, and other network resources, to control the user environment and set policies, and to deploy software to users and computers on the network. Learning to use the new AD features is an essential prerequisite to effectively migrate from the Windows NT 4.0 environment to Windows 2000.
This book, and Exam 70-222, will focus on both the planning and implementation phases of conducting a successful migration, with particular emphasis on the migration of complex, multi-domain networks.
Interestingly, Microsoft originally called the course mapped to this exam "Upgrading from Microsoft Windows NT 4.0 to Windows 2000." The name change reflects the fact that Windows 2000 is more than just a new version of an old operating system. The move to Windows 2000 is more than a mere upgrade; it is a true migration.
It may not seem so at first glance, especially for users of Windows 2000 Professional. The interface, though it has a different look and feel from Windows NT Workstation "out of the box," will be familiar in appearance to those who have used Windows 98, as well as those who have installed Internet Explorer 4.0's Active Desktop on their workstation machines. Under the hood, however, you will find big differences.
We think of an upgrade as an enhancement, or a set of enhancements, to a program or operating system. The transition from Windows 95 to Windows 98 (or, more currently, from Windows 98 to Windows ME) is an example of an upgrade. Some new features are added, some changes are made to the interface, but the basic operating system and how it works remain the same.
It's easy to understand why Microsoft first used the term upgrade to describe the move from Windows NT to Windows 2000, when you consider that Windows 2000 is based on the Windows NT kernel (the core code of the operating system). The new operating system even says, on the splash screen, "built on NT technology." When you install Windows 2000 from inside Windows 9x or Windows NT, you are given the option to upgrade to the new operating system.
However, when you do so, you get much more than the traditional upgrade (some enhancements to the basic operating system). What you get, particularly with the Server products, is an entirely new and different operating system that works differently in many ways. Some of the major differences include:
- Logical and physical structure of the network
- Trust relationships between domains
- Domain controller differences
- New directory services
- Security/authentication methods
- Degree and implementation of administrative control
Let's look briefly at each of these areas, and how Windows 2000 differs from its predecessors in each area.
Logical and Physical Network Structure
Experienced Windows NT administrators will find that one of the biggest differences between the old and new operating systems revolves around the structure of the network. Windows 2000 provides for dividing the network in two different ways: physically and logically.
The Physical Structure of the Network
Windows NT networks treated the physical structure as an element that was practically transparent to the operating system. IP networks were divided into subnets connected by routers, but this physical structure was not directly addressed within the network operating system (NOS). There was, for example, no way to control replication between domain controllers (DCs) so as to differentiate between those DCs that resided on the same subnet and those in another subnet that were connected over a slow wide area network (WAN) link.
Windows 2000 uses a new concept, that of sites, to provide administrators with a way to set up a replication topology that takes advantage of fast links to provide more frequent replication between domain controllers. At the same time, site configuration allows you to reduce or control the timing of replication traffic over slow links to prevent adverse effects on the performance of the network.
A Windows 2000 site is a collection of one or more "well connected" IP subnets as shown in Figure 1-1.
Microsoft defines "well connected" as a high-speed local area network (LAN) connection; the exact speed that meets that criteria is left up to the administrator. Some sources assume this to be 10 Mbps, or most commonly lOBaseT; however, Microsoft documentation in some places defines well connected subnets as those with connections as slow as 512 Kbps. When an administrator combines two or more subnets into a site, the domain controllers within that site will replicate their data to one another on a regular, frequent basis. This is called intra-site replication and occurs at five-minute intervals...
