Since Sliced Bread?
Douglas A. Hamilton WINDOWS NT NT: The Greatest Thing Since Sliced Bread? T'S OFFICIAL. Windows unlike OS/2, is not the only product in the family. Right around the corner is the NT is finally out of the Chicago technology that Microsoft will be using in DOS 7.0 and Windows 4.0. Earli oven. The pricing has est betas for software developers are I scheduled for early fall and products been set and delivery dates based on it should be out in 1994. Chicago is a rewrite of the same Win32 have been promised. Those API (application programming interface) seen on NT. Compared with NT, it leaves promises (back in May) out the security (how many of us need government-certified C2 security on our were that the base system personal machines?), portability to RISC processors and the OS/2 character-mode would ship within 60 days and POSIX subsystems. And it wouldn't surprise me if Unicode support were trimmed out or if the networking were and the Advanced Server version would ship 30 days unbundled. What Chicago leaves in is 32- bit flat virtual memory, preemptive multi later. So there's every chance that by the time you read tasking, threads, pipes and semaphores all the really good stuff in Win32. That be this, there'll be piles of Windows NT packages at your comes Windows 4.0. Subtract the graphi cal user interface and you get DOS 7.0. local computer store. Is there anyone left who wonders why developers are so excited about NT? It's After a false rumor that Microsoft might price NT at not just because NT is expected to do ex tremely well. -

SWEDIN WEBER STATE UNIVERSITY DAVIS ABSTRACT In 2006, IBM ended their support of OS/2, closing the book on an ambitious effort to create a modern operating system for the personal computer. IBM and Microsoft released the OS/2 operating system in December 1987 to replace the primitive DOS with a more sophisticated, preemptive multitasking operating system for personal computers. This article argues that OS/2 failed because of the U.S.-Japan Semiconductor Trade Agreement of 1986, subsequent accusations of DRAM chip dumping by the United States, and the resulting tariffs on Japanese memory chips, led to a memory chip shortage that drove up memory prices. -
Windows NT Architecture Previous Screen Gilbert Held Payoff Windows NT Is a Sophisticated Operating System for Workstations and Network Servers
50-30-19 Windows NT Architecture Previous screen Gilbert Held Payoff Windows NT is a sophisticated operating system for workstations and network servers. This article helps network managers to understand the communications capability of workstations and servers running on Windows NT, and data base administrators to determine the suitability of this platform for a structured query language (SQL) data base server. Introduction Windows NT is a 32-bit, preemptive multitasking operating system that includes comprehensive networking capabilities and several levels of security. Microsoft markets two version of Windows NT: one for workstations—appropriately named Windows NT Workstation—and a second for servers—Windows NT Server. This article, which describes the workings of the NT architecture, collectively references both versions as Windows NT when information is applicable to both versions of the operating system. Similarly, it references a specific version of the operating system when the information presented is specific to either Windows NT Workstation or Windows NT Server. Architecture Windows NT consists of nine basic modules. The relationship of those modules to one another, as well as to the hardware platform on which the operating system runs, is illustrated in Exhibit 1. Windows NT Core Modules Hardware Abstraction Layer The hardware abstraction layer (HAL) is located directly above the hardware on which Windows NT operates. HAL actually represents a software module developed by hardware manufacturers that is bundled into Windows NT to allow it to operate on a specific hardware platform, such as Intel X86, DEC Alpha, or IBM PowerPC. HAL hides the specifics of the hardware platform from the rest of the operating system and represents the lowest level of Windows NT. -
End-User Computing Security Guidelines Previous Screen Ron Hale Payoff Providing Effective Security in an End-User Computing Environment Is a Challenge
86-10-10 End-User Computing Security Guidelines Previous screen Ron Hale Payoff Providing effective security in an end-user computing environment is a challenge. First, what is meant by security must be defined, and then the services that are required to meet management's expectations concerning security must be established. This article examines security within the context of an architecture based on quality. Problems Addressed This article examines security within the context of an architecture based on quality. To achieve quality, the elements of continuity, confidentiality, and integrity need to be provided. Confidentiality as it relates to quality can be defined as access control. It includes an authorization process, authentication of users, a management capability, and auditability. This last element, auditability, extends beyond a traditional definition of the term to encompass the ability of management to detect unusual or unauthorized circumstances and actions and to trace events in an historical fashion. Integrity, another element of quality, involves the usual components of validity and accuracy but also includes individual accountability. All information system security implementations need to achieve these components of quality in some fashion. In distributed and end-user computing environments, however, they may be difficult to implement. The Current Security Environment As end-user computing systems have advanced, many of the security and management issues have been addressed. A central administration capability and an effective level of access authorization and authentication generally exist for current systems that are connected to networks. In prior architectures, the network was only a transport mechanism. In many of the systems that are being designed and implemented today, however, the network is the system and provides many of the security services that had been available on the mainframe. -
Page 1 of 3 How to Enable NTLM 2 Authentication 2/8/2012 Http
How to enable NTLM 2 authentication Page 1 of 3 Article ID: 239869 - Last Review: January 25, 2007 - Revision: 4.7 How to enable NTLM 2 authentication System Tip This article applies to a different version of Windows than the one you are using. Content in this article may not be relevant to you. Visit the Windows 7 Solution Center This article was previously published under Q239869 SUMMARY Historically, Windows NT supports two variants of challenge/response authentication for network logons: • LAN Manager (LM) challenge/response • Windows NT challenge/response (also known as NTLM version 1 challenge/response) The LM variant allows interoperability with the installed base of Windows 95, Windows 98, and Windows 98 Second Edition clients and servers. NTLM provides improved security for connections between Windows NT clients and servers. Windows NT also supports the NTLM session security mechanism that provides for message confidentiality (encryption) and integrity (signing). Recent improvements in computer hardware and software algorithms have made these protocols vulnerable to widely published attacks for obtaining user passwords. In its ongoing efforts to deliver more secure products to its customers, Microsoft has developed an enhancement, called NTLM version 2, that significantly improves both the authentication and session security mechanisms. NTLM 2 has been available for Windows NT 4.0 since Service Pack 4 (SP4) was released, and it is supported natively in Windows 2000. You can add NTLM 2 support to Windows 98 by installing the Active Directory Client Extensions. After you upgrade all computers that are based on Windows 95, Windows 98, Windows 98 Second Edition, and Windows NT 4.0, you can greatly improve your organization's security by configuring clients, servers, and domain controllers to use only NTLM 2 (not LM or NTLM). -
Windows 95, Windows 98, Windows 98SE, and Windows ME Courtesy of Nashville Home Linux Solutions
Important information for users of Windows 95, Windows 98, Windows 98SE, and Windows ME courtesy of Nashville Home Linux Solutions FACT: As of July 2006, Microsoft has officially ended support for Windows 95, Windows 98, Windows 98SE, and Windows ME (Millennium Edition). What does this mean for you? Microsoft©s end-of-support announcement means that users of Windows 95, 98, and ME will no longer receive security updates, bug fixes, and other patches for their computer©s operating system. It also means that future releases of Microsoft software (such as Media Player, Internet Explorer, and Outlook Express) will no longer support these operating systems. Users of these versions of Windows will not benefit from enhanced features and security in these new versions. Why should I be concerned? Windows 95, 98, and ME are based around the DOS operating system, an inherently insecure operating system. Users of DOS-based Windows will become increasingly at risk for viruses, spyware, malware, and system intrusions as new holes and exploits are discovered in these operating systems and the older software that runs on them. In addition, software vendors (including makers of anti-virus and other security products) will be phasing out support for these operating systems now that Microsoft has ended its support. If you are connecting your DOS-based Windows operating system to the Internet, you need to take action to secure your computer. What are my options? If you would like to continue to operate on your current hardware, you have a few options available to you: 1. Upgrade Windows Microsoft©s only currently-available Windows workstation operating system is Windows XP (Home or Professional). -
