Windows NT 4.0 Server Upgrade Guide 31

As a print server, Windows Server 2003 offers improvements in manageability, reliability, and

performance. Print driver management and reliability has been improved with kernel-mode driver

blocking, giving administrators control over driver installation on the server.

Windows Server 2003 maintains a high level of backward compatibility with Windows 2000 and

Windows NT 4.0 computing environments. Features such as IIS 5.0 isolation mode, a feature of

IIS 6.0, ensure compatibility with previous and third-party products. Adding a new server running

Windows Server 2003 to an existing Windows NT domain does not necessarily require replacing

existing software and infrastructure. The improved performance and management of Windows

Server make it an ideal operating system for consolidating existing services.

The following sections describe a few of the enhancements provided by Windows Server 2003.

For a more detailed look at these improvements, see Coexistence of Windows Server 2003 and

Windows NT 4.0 on the Windows Server 2003 Web site.

DFS

One of the biggest improvements for file servers is DFS, which takes an existing file infrastructure

and creates a single, logical view of files stored on multiple servers. This system is entirely

transparent to users who have the DFS client on their local computer. The DFS client is built into

Windows NT 4.0 and all later Microsoft operating systems. DFS makes files much easier to find,

because users do not need to know which server a file is on. DFS also improves scalability,

making it easy to add file servers or balance the workload among servers without disrupting users’

ability to find and access files.

Windows Server 2003 enhances the reliability of DFS by allowing a single server to host multiple

DFS roots, which means DFS can now be clustered for high availability and load balancing. You

can also store multiple copies of file shares for redundancy. FRS works with DFS to maintain

synchronized copies of data on file shares, so that in the event of a failure, DFS can transparently

redirect requests for data to a different server.

For better management on the corporate level, administrators can delegate control of a specific

portion of the DFS namespace rather than the entirety. This feature streamlines IT processes and

makes the entire infrastructure easier to maintain. DFS is fully integrated with Windows NT 4.0

security. One or more servers running Windows Server 2003 with DFS can help you replace or

aggregate your existing file structure into a single hierarchy that is easy to use and maintain.

Volume Shadow Copy Service

Volume Shadow Copy service is a new feature in Windows Server 2003 that enhances data

management in two primary ways. First, it allows for the creation of point-in-time copies of data on

a volume. Backups can be done online, without stopping server activity, and without the problems

of inconsistent data or open files being left out. Backups can also be scheduled to correspond

with periods of low network usage.

Volume Shadow Copy service maintains a set of previous versions of files, called shadow copies,

which can be used for data recovery when a file is damaged through human error, reducing the

frequency of restoring files from backup tapes. Shadow copies are incremental backups that

record only the files that have changed since the last backup. As a result, backups take up less
