2. Group Policy

Administrators can use Group Policy to define the settings and allowed actions for users and

computers. In contrast with local policy, Group Policy can be used to set policies that apply

across a specified site, domain, or organizational unit in Active Directory. Policy-based

management simplifies such tasks as system update operation, application installation, user

profiles, and desktop-system lockdown.

The Group Policy Management Console (GPMC) provides a new framework for managing

Group Policy. With GPMC, Group Policy becomes much easier to use, a benefit that enables

more organizations to better use Active Directory and take advantage of its management

features.

3. Server Performance

In internal tests, Windows Server 2003 shows dramatic performance gains over previous

versions of Windows server operating systems. For example, file and Web server

performance is two times faster than Windows NT Server 4.0. While an organization's

performance gains may vary because of unique network and computer settings, Microsoft is

confident that the improved performance of Windows Server 2003 will help deliver faster

service for network solutions.

4. Shadow Copies of Shared Folders

As part of Volume Shadow Copy service, this feature enables administrators to configure

point-in-time copies of critical data volumes without service interruption. These copies can

then be used for service restoration, archival purposes, or restoration. Users can retrieve

archived versions of their documents that are transparently maintained on the server.

Productivity is improved by the ability to better recover documents.

5. IIS 6.0 and the .NET Framework

IIS 6.0 is a full-featured Web server that enables Web applications and XML Web services.

IIS 6.0 has been completely rearchitected with a new fault-tolerant process model that greatly

boosts the reliability of Web sites and applications.

Now, IIS can isolate an individual Web application or multiple sites into a self-contained

process (called an application pool) that communicates directly with the operating system

kernel. This feature increases throughput and capacity of applications while offering more

headroom on servers, effectively reducing hardware needs. These self-contained application

pools prevent one application or site from disrupting the XML Web services or other Web

applications on the server.

IIS also provides health monitoring capabilities that discover, recover, and help prevent Web

application failures. On Windows Server 2003, ASP.NET natively uses the new IIS process

model. These advanced application health and detection features are also available to

existing applications running under IIS 4.0 and IIS 5.0, and most applications do not need tp

be modified.

The .NET Framework provides the programming model for building, deploying, and running

Web-based applications and XML Web services in the IIS environment. It provides a

productive, standards-based, multiple-language environment for integrating existing
