Windows 2000 Datacenter Server
Windows
2000 Professional
Windows
2000 professional includes many features and enhancements that provide a simpler
user interface, improved communications and support for mobile users, and broad
hardware and software compatibility. Some of the improvements from Windows NT
4.0 include:
·
Synchronization
manager. Compares items on the network to items that you opened or updated while
working offline. Synchronization occurs when you log on and Windows 2000 saves
any changes made offline to files and folders, Web pages, or e-mail messages to
the network.
·
Internet
printing Protocol (IIP). Enables users to install printer drivers or send
documents to any printer on a windows 2000-based network that is connected to an
intranet or the internet. You can also print to a Uniform Resource Locator (URL)
over an intranet or the internet.
·
Plug and Play
Manager. Enhances previous Plug and Play functionality and allows:
·
Automatic and
dynamic reconfiguration of installed hardware
·
Loading of
appropriate drivers
·
Registration
for device notification events
·
Changeable and
removable devices
·
Kerberos
version 5 protocol. Allows users to log on only once to gain access to network
resources, providing faster authentication and network response. The Kerberos V5
protocol is an Internet security standard authentication protocol and is the
primary security protocol for Windows 2000 domains.
·
Encrypting File
System (EFS). Strengthens security by encrypting files on your hard disk so that
no one can access them without using the correct password.
·
Internet
Protocol Security (IPSec). Encrypts Transmission Control Protocol (TCP / IP) traffic to secure communications
within an internet and provide the highest levels of security for virtual
private network (VPN) traffic across the Internet
·
Smart card
support. Enables portability of credentials and other private information
between computes at work, at home, or on the road. This eliminates the need to
transmit sensitive information, such as authentication tickets and private keys,
over networks.
·
Secondary Logon
Service. Enables you to launch applications by using a different user account
than the one that was used to log on the computer. Administrators can log with a
standard user account and launch administrative tools by using an administrator
account, without having to log off and then log on again with an administrator
account.
·
Setup Manager
wizard. Guides you through the process of choosing the elements and settings for
a group of computers and save those settings in installation script files.
·
Microsoft
Windows Installer. Manages application installation, modification, repairs and
removal. The installer provides a standard format for managing the components of
a software package, plus an application programming interface (API) for managing
applications and tools.
Windows
2000 Server
Windows
2000 Server contains all of the features that are included in Windows 2000
Professional. Windows 2000 server supports a maximum of four processors. It also
supports physical memories of up to 4 gigabyte (GB). Windows 2000 Server include
te follow benefits.
Active
Directory
Active
directory
directory service is included in each of the windows 2000 server products. It
provides a single, consistent, open set of interfaces for performing common
administrative tasks, such as adding new users, managing printers, and locating
resources throughout an enterprise.
Active
directory addresses the following business needs:
 | Simplified
administration. Active directory provides a single location to store
information about users and resources. |
| Flexible
administration. Active directory increases administrative flexibility by
enabling you to delegate authority over users and computers to other users
or groups, such as administrators. |
| Scalability.
In Windows NT 4.0, domains have a practical limit of 40000 users. Therefore,
you must create many domains for a large organization. A Windows 2000 Active
Directory domain ca contain millions of users. |
| Standards-based
protocol. Access to active directory is achieved through the Lightweight
Directory Access Protocol (LDAP). Applications use LDAP instead of
proprietary protocols to access and change information in Active Directory. |
Simplified
Management
Windows
2000 Server helps administrators easily manage their networks from a central
location. It offers several features and enhancements that
provide the foundation for simplifying management of your entire network.
| Group
policy. Gives administrators more control over which users have access to
specific workstations, data and applications. Group Policy allows
administrators to define and control the state of computer and user accounts
within an organization. |
| DNS
dynamic update protocol. Reduces network administration costs by reducing
the need for manual editing of the DNS database each time that a change
occurs in a DNS client’s configuration. |
| Terminal
Services. Allows client computes to access Windows-based applications
running entirely on the server and supports multiple client sessions on the
server. The server manages all computing resources for connected client
computers and provides all logged-on users with their own environment. |
Windows
2000 Advanced Server
In
additional to provide the features in Windows 2000 Server, Windows 2000 Advanced
Server includes:
·
Enterprise
memory architecture. Enables applications that perform transaction processing or
decision support on large data sets to keep more data in memory, resulting in
greatly improved performance. Windows 2000 advanced Server supports physical
memories up to 8 GB
·
Symmetric
multiprocessing (SMP) scalability. Supports up to eight processors
· Windows Clustering. Enables you to connect multiple servers to form a cluster of servers that work together as a single system. Windows Clustering provides the following benefits:
| Increased
availability. Provides increased availability for mission-critical
applications, including the ability to automatically detect the failure of
an application and quickly restart it on a different server. In addition, if
one server in the cluster fails, another server in the cluster can be used
to restore service to users. |
| Network
Load Balancing. Provides increased availability and scalability for network-based
services, such as TCP/IP and WEB services. |
Windows
2000 Datacenter Server
Windows
2000 Datacenter Server builds upon the features in Windows 2000 Advanced Server,
Making it the most powerful and functional Server operating system that
Microsoft has ever offered.
Key
benefits of Windows 2000 Datacenter Server include
| SMP
scalability. Supports up to 32 processors. |
| Physical
memory. Supports physical memories of up to 64 GB |
Like
windows 2000 Advanced Server, Windows 2000 Datacenter Server includes both
clustering and load balancing services as standard features. Windows 2000
Datacenter Server provides optimal functionality for:
| Large
data warehouses |
| Econometric
analysis |
| Large-scale
simulations in science and engineering |
| Online
transaction processing |
| Server
consolidation Projects |
| Large-scale
Internet service providers (ISPs) and Web-site hosting |
