Win2000 upgrade to Win2003 10 major functions cause

Windows Server 2003 is based on the reliable Windows 2000 Server series, it integrates a powerful application environment to develop new XML Web services and improved applications Programs that will significantly increase process efficiency. The following major new features and improvements are provided for organizations considering upgrading from Windows 2000 Server to Windows Server 2003.

1. Active Directory Improvements

Introduced in Windows 2000 Microsoft Active Directory? Services simplify the management of complex network directories and make it easy for users to find resources even on the largest networks. This enterprise directory service is extensible, built entirely on Internet-based technology, and fully integrated with Windows .NET Server 2003 Standard Edition, Windows .NET Server 2003 Enterprise Edition, and Windows .NET Server 2003 Datacenter Edition .

Windows Server 2003 provides many simple and easy-to-use improvements and new features for Active Directory, including cross-forest trust, the ability to rename domains, and the ability to disable attributes and categories in the schema so that they can change their definitions. Features.

2. Group Policy Management Console

Administrators can use Group Policy to define settings and actions that users and computers can perform. Enterprise users can use Group Policy to set policies that apply to a specified site, domain, or organizational unit in Active Directory. Policy-based management simplifies tasks such as system update operations, application installation, user profiles, and desktop system lockouts.

The Group Policy Management Console (GPMC) is expected to be available as an add-on component to Windows Server 2003, which provides a new framework for managing Group Policy. With GPMC, Group Policy will be easier to use, and this advantage will enable more enterprise users to better use Active Directory and take advantage of its powerful management capabilities.

3. Policy Result Sets

The Policy Results Set (RSoP) tool allows administrators to view group policy effects on a target user or computer. With RSoP, enterprise users will have powerful and flexible basic tools to plan, monitor group policies, and resolve group policy issues.

RSoP is a structure provided in the form of a set of Microsoft Management Console (MMC) snap-ins. These snap-ins allow administrators to determine and analyze the current set of policies in two modes: login mode and plan mode. In login mode, administrators can access information that has been applied to a specific target. In scheduling mode, administrators can see how the policy will be applied to the target and then check the results before deploying the changes to the group policy.

4. Volume Shadow Copy Recovery

As part of the Volume Shadow Copy service, this feature enables administrators to configure point-in-time copies of critical data volumes without disrupting service. These copies can then be used for service restoration or archiving. Users can retrieve archived versions of their documents, and those saved on the server are invisible.

5. Internet Information Services 6.0

Internet Information Services (IIS) 6.0 is a full-featured Web server with Web applications and XML Web services enabled. IIS 6.0 was completely rebuilt using the new fault-tolerant process model, which greatly improved the reliability of Web sites and applications.

Now, IIS can separate a single Web application or multiple sites into a separate process called an application pool, which communicates directly with the operating system kernel. This feature increases throughput and application capacity while providing more active space on the server, effectively reducing hardware requirements. These separate application pools will prevent an application or site from corrupting XML Web services or other Web applications on the server.

IIS also provides status monitoring to discover, recover, and prevent web application failures. On Windows Server 2003, Microsoft ASP.NET uses the new IIS process model locally. These advanced application status and detection features are also available for existing applications running under Internet Information Server 4.0 and IIS 5.0, most of which do not require any modifications.

6. Integrated .NET Framework

The Microsoft .NET Framework is a Microsoft .NET-connected software for building, deploying, and running web applications, smart client applications, and XML Web services. And the programming model of technology that exposes their functionality programmatically on the network using standard protocols such as SOAP, XML, and HTTP.

The .NET Framework provides an efficient, standards-based environment for integrating existing investments with next-generation applications and services.

In addition, it helps enterprise users solve problems with deploying and operating Internet-wide applications.

With the .NET Framework fully integrated into the Windows Server 2003 operating system, developers can free themselves from writing "pipeline" code so they can focus on real business value. The .NET framework takes into account integration and management details, reducing coding complexity and increasing consistency.

7. Command Line Management

The command line structure of the Windows Server 2003 family has been significantly enhanced to allow administrators to perform most administrative tasks without the need for a graphical user interface. The most important is the ability to perform most tasks by using Windows Management Instrumentation (WMI) enabled information store. This WMI Command Line (WMIC) feature provides a simple command line interface that interoperates with existing shell and utility commands and can be easily extended by scripts or other management-oriented applications.

In summary, the more powerful command-line features of the Windows Server 2003 family, combined with off-the-shelf scripts, can compete with other features of operating systems that typically have higher cost of ownership. Administrators who are used to managing UNIX or Linux systems using the command line can continue to manage from the command line in the Windows Server 2003 family.

8. Cluster (8-node support)

This service is only for Windows Server 2003 Enterprise Edition and Windows Server 2003 Datacenter Edition, which is a mission-critical application (such as database, messaging system) And file and print services) provide high availability and scalability. Maintain consistent communication by enabling multiple servers (nodes) to work together. If a node in the cluster is unavailable due to an error or repair, the other node will begin to provide the service immediately, a process called failover. Users who are accessing the service will continue their activities without being aware that the service is now being served by another server (node).

Both Windows Server 2003 Enterprise Edition and Windows Server 2003 Datacenter Edition support server cluster configurations of up to 8 nodes.

9. Secure Wireless LAN (802.1X)

According to the Windows Server 2003 family of 802.1X support, companies can look for a security model that will ensure that all physical access is Authorized and encrypted. With 802.1X-based wireless access points or options, companies can ensure that only trusted systems can connect to and exchange packets with protected networks. Because the dynamic key is determined by 802.1X, 802.1X wireless network encryption will be significantly improved by addressing many of the known issues associated with Wired Device Privacy (WEP), which is used by IEEE 802.11 networks.

This feature provides security and performance improvements for wireless local area networks (LANs) such as automatic key management, user authentication, and authorization before accessing the LAN. When wired Ethernet is used in public places, it also provides access control to the Ethernet network.

10. Emergency Management Services: Headless Server Support

The Headless Server feature allows IT administrators to have no monitors, VGA display adapters, keyboards or mice. Ability to install and manage computers. Emergency Management Services is a new feature that enables IT administrators to perform remote management and system recovery tasks over the network or other standard remote management tools and mechanisms when they are unable to use the server.
