Microsoft acquired networking technology from 3Com Corporation and incorporated it into products like LAN Manager and Windows. None provided the stability of Novell NetWare until Windows NT Server, which was Microsoft's first commercially successful venture into networking. Key features of Windows 2000/NT included Active Directory for improved object management, security features like Encrypting File System, and management tools like the Microsoft Management Console.

1. Windows NT/2000
 Microsoft acquired most of its networking
technology from 3Com Corporation.
 Microsoft incorporated the 3Com
technology in its main product lines, starting
with LAN Manager, a dedicated file and print
server

2. Windows NT/2000
 Microsoft then went on to extend its
networking technology into workgroup
environments with the release of
Windows for Workgroups and Windows
95.

3. Windows NT/2000
 None of these Microsoft products
offered the stability or performance of a
dedicated Novell NetWare server--but this
changed with the advent of Windows NT
Server.

4. Windows NT/2000
 Windows NT 4 could be considered
Microsoft’s first commercially
successful venture into the world of
networking.

5. Windows NT/2000
 Sure, they had LAN Manager and they had
Windows NT 3.51, but it really wasn’t until
NT 4 was released that the marketplace really
started to jump on the Microsoft networking
bandwagon.

6. Windows NT/2000
 Windows NT 4 Server is an
enterprise-oriented product that can
compete head-to-head with Novell
NetWare.

7. Windows NT/2000
 Windows NT 4 Server (and Windows NT
4 Workstation) is a genuine commercial-
class operating system--Microsoft's first
entry into the marketplace of enterprise-
oriented data processing.

8. Windows NT/2000
 One final key point that separates
Windows NT 4 Server from NetWare is that
Windows NT 4 Server is clearly more than
just a file and print server--Windows NT 4
Server is an application server.

9. Windows NT/2000
 Unlike NetWare, which requires
vendors to write NLMs, Windows
NT 4 Server can host conventional,
Windows-based applications.

10. Windows NT/2000
 Windows NT Server can be hosted by
systems using Intel or DEC (Digital Equipment Corp.)
Alpha processors. Earlier in its history,
Windows NT Server also supported MIPS
(Millions of Instructions Per Second) processor systems;
however, MIPS will no longer be supported as
of the release of Windows 2000.

11. Windows NT/2000
 Support for NT on the PowerPC has also been
phased out by both Motorola and IBM, and it is
unlikely that Microsoft will continue to support
the PowerPC architecture in subsequent releases.

12. Windows NT/2000
 The basic functions of Windows NT Server
are consistent across all these types of systems,
but additional application programs might not be
available for all processor types. For this reason,
Intel-based machines are deployed in the
majority of Windows NT Server installations.

13. Windows NT/2000
 In addition to supporting different
types of systems, Windows NT supports
Symmetrical Multi-Processing (SMP);
therefore, Windows NT can immediately
take advantage of systems with multiple
CPUs.

14. Windows NT/2000
 Windows NT Server runs as a non-
dedicated operating system--you can use the
same system for desktop applications if you so
desire. In fact, Windows NT Server is very
similar to its desktop counterpart, Windows
NT Workstation.

15. Windows NT/2000
 Detailed analysis has shown that the
operating system core is the same for both
products. Windows NT Server has, however,
been fine tuned for server performance and
includes additional software not available for
Windows NT Workstation.

16. Windows NT/2000
 You can manage a Windows NT Server
from the local keyboard and monitor and, as
in the case of NetWare, you can manage it
from other workstations in the network.

17. Windows NT/2000
 In terms of security, Windows NT
offers two types of security models:
1) Workgroups (Peer to Peer)
1) Domains (Client/Server)

18. Windows NT/2000
 In a workgroup model, the user authentication
process occurs on each system in the workgroup.
Other workgroup systems "trust" that each
system has performed the authentication.
 From a broader perspective, workgroups are
informal groupings of systems that elect to share
resources with one another.

19. Windows NT/2000
 In a domain model, however, all users
are authenticated by a central server
(termed the domain controller). Using a
centralized server provides greater control
and security.

20. Windows NT/2000
 Unlike workgroups, domains can be
interconnected. When you interconnect
domains, you can establish trust
relationships between them so a user
logged on to one domain can access
resources in another domain without
being forced to log on to the second
domain.

21. Windows NT/2000
 Although this approach works well in
simple organizations, trust relationships can
grow very complex in large organizations.

22. Windows NT/2000
 For that reason, Microsoft has moved
toward global, NDS-like directory services
called Active Directory Services (ADS) with
Windows 2000.

23. Windows NT/2000
 A directory service is just a way to
keep track of all that stuff on your
network. It is a way to manage it,
secure it, and make it available to
your users.

24. Windows NT/2000
 Directory Services is the major difference
between NT 4 and Windows 2000. As a matter
of fact, many of the other differences spring
from the fact that Windows can now use a
directory service.

25. Windows NT/2000
 In Windows NT 4, object management
was done at the domain level, and Microsoft
suggested that you have a maximum of
40,000 objects per domain.With Windows
2000, you can support millions of objects per
domain or partition.

26. Windows NT/2000
 Windows 2000 uses a system called
the Global Catalog to provide a single
view of the directory objects that may be
stored in multiple domains.

27. Windows NT/2000
 Windows NT has been evolving for
many, many years. Starting with the
first version in 1993, this modular
approach to an operating system has
proven itself to be secure and stable.

28. Windows NT/2000
 The Windows NT platform now
has a commanding hold of the
majority share of the business
market and looks to continue its
winning ways with Windows 2000
and beyond.

29. Features of Windows 2000/NT
Setup Manager
Setup Manager provides a graphic interface to the users to make
installation scripts.
Faster Multitasking
It allows user to run multiple programs and perform different
tasks such as browsing, listening music, downloading and
working on the files at the same time. In Multitasking 32-bit
architecture.
Troubleshooters
It assists users to troubleshoot, optimize and configure a lot of
functionalities of Windows 2000 Professional, which results in
greater performance and greater productivity.
Personalized Menu
It adapts the start menu to show the applications that you most work
on.
