Microsoft Windows Server 2003 Inside Out The amount of effort involved in the move to Windows Server 2003 largely depends on whether you are currently using Windows NT or Windows 2000. For example, consider one of the most significant features in Windows Server 2003, the Active Directory directory service.

The change in network management that the move from Windows NT domains to Active Directory entails presents a set of architectural and operational questions for both Information Technology (IT) and business management. Implementing Active Directory requires defining and creating a Domain Name System (DNS) namespace and an Active Directory forest and domain structure. Security, user rights, network administration, Group Policy, and so on are handled by Active Directory, so a large number of disparate aspects of the network and business must be taken into account in the design process not a trivial task. Moving from Windows 2000 Server to Windows Server 2003, on the other hand, requires far less planning and administrative effort, because the DNS design and Active Directory namespace are already done. Although there are some new features and management changes, the changes to Active Directory between Windows 2000 and Windows Server 2003 are nominal, especially when compared to the switch from Windows NT domains to Active Directory.

The same is true to a great extent throughout the operating system the change between Windows NT 4 and Windows Server 2003 is substantial, while the difference when moving from Windows 2000 to Windows Server 2003 is much less so. Whether you can upgrade an existing server to Windows Server 2003 depends on hardware compatibility, available disk space, and adequate hardware resources (central processing unit [CPU], random access memory [RAM]). Upgrading to Windows Server 2003 is also dependent upon the existing version of the Windows operating system Setup upgrades only Windows NT 4 Server (with Service Pack 5 or later) and Windows 2000 Server to Windows Server 2003. Tip Get tools for migrating to Windows Server 2003 In those cases in which you want to start with a clean installation of Windows Server 2003 and migrate your users, computers, groups, and security settings to a new Active Directory forest and domain, you must determine which domains and security principals will be migrated and then select the migration tools to use. Although there are several migration tools available from independent vendors, Microsoft does supply migration capability in its Active Directory Migration Tool (ADMT). For more information on migration, see 9, Migrating to Windows Server 2003.

When deciding whether to upgrade or perform a migration, you must examine several aspects of your current environment, starting with the most fundamental: Is the existing hardware adequate It s not just a case of meeting minimum system requirements; rather, you must consider whether system performance meets your real-world needs. If it s slow now, it s not going to get any better. When considering existing systems, make sure that you factor in all the services and applications that will be running on the server. Another thing to consider is the history of each existing server. Has it been in place for a number of years, with the inevitable wear and tear that that entails Is a lot of additional software installed Have a number of patches and service packs been applied If so, you might want to start with a clean installation, even if you are using existing hardware to do so. On the other hand, if you have a server with a complex configuration and it is stable, you might want to take advantage of all the work that has gone into it and perform an upgrade. You should consider whether sufficient hard disk drive space is available. At least 2 gigabytes (GB) of disk space and preferably more is required for an upgrade of Windows Server 2003. This can be an issue on systems that have small partitions, such as those using file allocation table (FAT) partitions, which might not be large enough to support an upgrade at all, rather than the NTFS file system. Tip
Don t upgrade servers you should replace Hardware has dropped in price considerably over the past few years, making new servers and components more affordable than ever. This makes it easier to ensure that servers have the capabilities they need to provide the services you require. You might also find used servers that meet your needs at online auction sites, such as eBay. Bid wisely and with reputable sellers and you could get some great deals.
