Why Upgrade?

There are many reasons to upgrade. One reason is to keep pace with new technology. However,

the time and financial investment in making a change can be substantial, even when upgrading a

single computer. The return on investment must be evaluated. Windows Server 2003 provides

many advantages over earlier Windows server versions. Many of these benefits fall under the

umbrella of enhancing system security. Other significant new features help make this version of

Windows the most reliable, scaleable, and dependable operating system that Microsoft has

delivered. As a result, the return on investment of moving to Windows Server 2003 can be quickly

realized.

New features include a completely rearchitected version of IIS 6.0 with ASP.NET and

improvements to Active Directory that ease management, including cross-forest trusts and Active

Directory in Application Mode (AD/AM). Other features include Volume Shadow Copy service for

making point-in-time copies of critical data that can be used for restoration or archival purposes,

integrated public key infrastructure (PKI) support using Kerberos 5.0, improved Terminal Services,

clustering with 8-node support, and intelligent file services.

The following table summarizes the key benefits of upgrading.
