Windows NT/2000 Microsoft acquired most of its networkingtechnology from 3Com Corporation. Microsoft incorporated the 3Comtechnology in its main product lines, startingwith LAN Manager, a dedicated file and printserver
Windows NT/2000 Microsoft then went on to extend itsnetworking technology into workgroupenvironments with the release ofWindows for Workgroups and Windows95.
Windows NT/2000 None of these Microsoft productsoffered the stability or performance of adedicated Novell NetWare server--but thischanged with the advent of Windows NTServer.
Windows NT/2000 Windows NT 4 could be consideredMicrosoft’s first commerciallysuccessful venture into the world ofnetworking.
Windows NT/2000 Sure, they had LAN Manager and they hadWindows NT 3.51, but it really wasn’t untilNT 4 was released that the marketplace reallystarted to jump on the Microsoft networkingbandwagon.
Windows NT/2000 Windows NT 4 Server is anenterprise-oriented product that cancompete head-to-head with NovellNetWare.
Windows NT/2000 Windows NT 4 Server (and Windows NT4 Workstation) is a genuine commercial-class operating system--Microsofts firstentry into the marketplace of enterprise-oriented data processing.
Windows NT/2000 One final key point that separatesWindows NT 4 Server from NetWare is thatWindows NT 4 Server is clearly more thanjust a file and print server--Windows NT 4Server is an application server.
Windows NT/2000 Unlike NetWare, which requiresvendors to write NLMs, WindowsNT 4 Server can host conventional,Windows-based applications.
Windows NT/2000 Windows NT Server can be hosted bysystems 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 asof the release of Windows 2000.
Windows NT/2000 Support for NT on the PowerPC has also beenphased out by both Motorola and IBM, and it isunlikely that Microsoft will continue to supportthe PowerPC architecture in subsequent releases.
Windows NT/2000 The basic functions of Windows NT Serverare consistent across all these types of systems,but additional application programs might not beavailable for all processor types. For this reason,Intel-based machines are deployed in themajority of Windows NT Server installations.
Windows NT/2000 In addition to supporting differenttypes of systems, Windows NT supportsSymmetrical Multi-Processing (SMP);therefore, Windows NT can immediatelytake advantage of systems with multipleCPUs.
Windows NT/2000 Windows NT Server runs as a non-dedicated operating system--you can use thesame system for desktop applications if you sodesire. In fact, Windows NT Server is verysimilar to its desktop counterpart, WindowsNT Workstation.
Windows NT/2000 Detailed analysis has shown that theoperating system core is the same for bothproducts. Windows NT Server has, however,been fine tuned for server performance andincludes additional software not available forWindows NT Workstation.
Windows NT/2000 You can manage a Windows NT Serverfrom the local keyboard and monitor and, asin the case of NetWare, you can manage itfrom 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 authenticationprocess occurs on each system in the workgroup.Other workgroup systems "trust" that eachsystem has performed the authentication. From a broader perspective, workgroups areinformal groupings of systems that elect to shareresources with one another.
Windows NT/2000 In a domain model, however, all usersare authenticated by a central server(termed the domain controller). Using acentralized server provides greater controland security.
Windows NT/2000 Unlike workgroups, domains can beinterconnected. When you interconnectdomains, you can establish trustrelationships between them so a userlogged on to one domain can accessresources in another domain withoutbeing forced to log on to the seconddomain.
Windows NT/2000 Although this approach works well insimple organizations, trust relationships cangrow very complex in large organizations.
Windows NT/2000 For that reason, Microsoft has movedtoward global, NDS-like directory servicescalled Active Directory Services (ADS) withWindows 2000.
Windows NT/2000 A directory service is just a way tokeep track of all that stuff on yournetwork. It is a way to manage it,secure it, and make it available toyour users.
Windows NT/2000 Directory Services is the major differencebetween NT 4 and Windows 2000. As a matterof fact, many of the other differences springfrom the fact that Windows can now use adirectory service.
Windows NT/2000 In Windows NT 4, object managementwas done at the domain level, and Microsoftsuggested that you have a maximum of40,000 objects per domain.With Windows2000, you can support millions of objects perdomain or partition.
Windows NT/2000 Windows 2000 uses a system calledthe Global Catalog to provide a singleview of the directory objects that may bestored in multiple domains.
Windows NT/2000 Windows NT has been evolving formany, many years. Starting with thefirst version in 1993, this modularapproach to an operating system hasproven itself to be secure and stable.
Windows NT/2000 The Windows NT platform nowhas a commanding hold of themajority share of the businessmarket and looks to continue itswinning ways with Windows 2000and beyond.
