Windows NT 4.0 Server Upgrade Guide 4

Key Benefits

Benefit Description

Reduce costs Case studies have shown that organizations can recoup the cost of upgrading to

Windows Server 2003 in 6 to 18 months with a 20 to 30 percent reduction in total

cost of ownership. Windows Server 2003 has a 50-percent improved uptime over

Windows NT Server 4.0 and reduces costs by reducing down time. New features

such as the Volume Shadow Copy service have shown to reduce file recovery

incidents by 90 percent.

Reduce risk Security enhancements to Windows Server 2003 help reduce risk by keeping the

system more secure than in previous versions and by ensuring mission-critical data

is better protected than it was in previous versions.

§ To reduce the surface area exposed to an attacker, many services are no longer

installed by default and many run with reduced permissions.

§ Software Restriction Policies help to mitigate security risks by preventing users

from executing harmful applications.

§ Studies have shown that approximately 60 percent of corporate data is stored

on the desktop, unprotected. New features in Windows Server 2003 help to

protect the computers that are on your network by redirecting where the My

Documents data is stored: on the server as encrypted files. This change also

facilitates more efficient backup through Shadow Copy services.

Increase

productivity

Many features of Windows Server 2003 have significant performance improvements

over Windows NT Server 4.0. Improvements have been measured for file, Web,

directory, and transaction services compared to Windows NT Server 4.0.

Take advantage

of the migration

ecosystem

Powerful tools are available to help ensure a successful upgrade, including:

§ IIS 6.0 migration tool

§ Active Directory Migration Tool (ADMT)

§ Application Compatibility Toolkit 3.0

§ Remote Installation tool

§ Automated Deployment Services

§ Many other tools available by third-party vendors

Top 10 Reasons to Upgrade

Here are the major new features and improvements for organizations considering upgrading from

Windows NT Server 4.0:

1. Active Directory

Active Directory simplifies the administration of complex network directories and makes it

easy for users to locate resources on even the largest networks. This enterprise-class

directory service is scalable, built from the ground up using Internet-standard technologies,

and fully integrated at the operating-system level in Windows Server 2003, Standard Edition;

Windows Server 2003, Enterprise Edition; and Windows Server 2003, Datacenter Edition.

Windows Server 2003 provides numerous ease-of-use improvements to Active Directory and

new features, including cross-forest trusts, the ability to rename domains, and the ability to

deactivate attributes and classes in the schema so that their definitions can be changed.
