investments with next-generation applications and services as well as the agility to solve the

challenges of deployment and operation of Internet-scale applications. Existing applications

can be repackaged as XML Web services, and UNIX applications can be integrated or even

upgraded into the solution with less work than in the past.

6. Terminal Services

Terminal Server enables administrators deliver Windows-based applications, or the Windows

desktop itself, to virtually any computing device—including those that cannot run Windows.

When users run an application on Terminal Server, the application execution takes place on

the server, and only keyboard, mouse, and display information is transmitted over the

network. Users see only their own individual sessions, which are managed transparently by

the server operating system, and remain independent of any other client session.

Remote Desktop for Administration builds on the remote administration mode of Windows

2000 Terminal Services. In addition to the two virtual sessions that are available in Windows

2000 Terminal Services remote administration mode, an administrator can also remotely

connect to the real console of a server.

Terminal Server can enhance an enterprise's software deployment capabilities for a variety of

scenarios that remain difficult to solve using traditional application distribution technologies.

7. Clustering (8-Node Support)

Available only in Windows Server 2003, Enterprise Edition and Windows Server 2003,

Datacenter Edition, this service provides high availability and scalability for applications such

as databases, messaging systems, and file and print services. Clustering works by enabling

multiple servers (nodes) to remain in constant communication. If one of the nodes in a cluster

becomes unavailable as a result of failure or maintenance, another node immediately begins

providing service, a process known as failover. Users who are accessing the service continue

their activities, unaware that service is now being provided from a different server (node).

Both Windows Server 2003, Enterprise Edition and Windows Server 2003, Datacenter

Edition, support server cluster configurations of up to eight nodes.

8. Integrated PKI Support Using Kerberos 5.0

Using Certificate Services and certificate management tools, organizations can deploy their

own PKI. With PKI, administrators can implement standards-based technologies, such as

smart card logon capabilities, client authentication using Secure Sockets Layer (SSL) and

Transport Layer Security (TLS) protocols, e-mail security improvements, digital signatures,

and connectivity through Internet Protocol security (IPSec).

Using Certificate Services, administrators can set up and manage certification authorities that

issue and revoke X.509 V3 certificates. This means that organizations do not have to depend

on commercial client authentication services, although they can be integrated into an

organization's PKI.

Kerberos 5.0 is a mature, industry-standard network authentication protocol. With Kerberos

5.0 support, a fast, single-logon process gives users the access they need to enterprise

resources, as well as to other environments that support this protocol. Additional benefits
