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

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.

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.

Windows NT/2000

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

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.

Windows NT/2000

Windows NT/2000

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

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.

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.

Windows NT/2000

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

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.

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.

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.

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.

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.

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.

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.

Windows NT/2000

In terms of security, Windows NT offers two types of security models:

1) Workgroups (Peer to Peer)

1) Domains (Client/Server)

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.

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.

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.

Windows NT/2000

Although this approach works well in simple organizations, trust relationships can grow very complex in large organizations.

Windows NT/2000

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

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.

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.

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.

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.

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.

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.
