It is a processor-independent, operating system. The first version of Windows NT was and was produced for and.
It was intended to complement consumer versions of that were based on (including through ). Gradually, the Windows NT family was expanded into Microsoft's general-purpose operating system product line for all, deprecating the family. 'NT' formerly expanded to 'New Technology' but no longer carries any specific meaning.
Starting with, 'NT' was removed from the product name and is only included in the product version string. NT was the first purely version of Windows, whereas its consumer-oriented counterparts, Windows 3.1x and Windows 9x, were 16-bit/32-bit hybrids. It is a multi-architecture operating system. Initially, it supported several, including, and later. The latest versions support (more specifically IA-32 and ) and.
Major features of the Windows NT family include, and. Contents.
Naming It has been suggested that intended the initialism 'WNT' as a play on,. However, the project was originally intended as a follow-on to and was referred to as 'NT OS/2' before receiving the Windows brand. One of the original NT developers, states that the name was taken from the original target processor—the, code-named N10 ('N-Ten').
A 1998 question-and-answer session with, reveal that the letters were previously to 'New Technology' but no longer carry any specific meaning. The letters were dropped from the names of releases from Windows 2000 and later, though Microsoft described that product as being 'Built on NT Technology'.
Major features A main design goal of NT was hardware and software portability. Various versions of NT family operating systems have been released for a variety of processor architectures, initially, and, with, and supported in later releases. The idea was to have a common code base with a custom (HAL) for each platform.
However, support for MIPS, Alpha, and PowerPC was later dropped in Windows 2000. Broad software compatibility was achieved with support for several 'personalities', including, and APIs – the latter two were phased out starting with Windows XP.
Partial compatibility was achieved via an integrated – although this feature is being phased out in the architecture. NT supported per-object (file, function, and role) allowing a rich set of security permissions to be applied to systems and services. NT supported Windows network protocols, inheriting the previous OS/2 networking, as well as networking (for which Microsoft would implement a TCP/IP stack derived at first from a -based stack from, then later rewritten in-house).
Windows NT 3.1 was the first version of Windows to use 32-bit flat virtual memory addressing on 32-bit processors. Its companion product, Windows 3.1, used segmented addressing and switches from 16-bit to 32-bit addressing in pages.
Windows NT 3.1 featured a core kernel providing a system API, running in (ring 0 in x86; referred to in Windows NT as 'kernel mode' on all platforms), and a set of user-space environments with their own APIs which included the new Win32 environment, an OS/2 1.3 text-mode environment and a POSIX environment. The full kernel could interrupt running tasks to other tasks, without relying on user programs to voluntarily give up control of the CPU, as in Windows 3.1 Windows applications (although MS-DOS applications were preemptively multitasked in Windows starting with Windows 1.0). Notably, in Windows NT 3.x, several I/O driver subsystems, such as video and printing, were subsystems. Kulturista-web font. In Windows NT 4, the video, server, and printer spooler subsystems were moved into kernel mode. Windows NT's first was strongly influenced by (and programmatically compatible with) that from Windows 3.1; Windows NT 4's interface was redesigned to match that of the brand new, moving from the to the design., a journaled, secure file system, was created for NT. Windows NT also allows for other installable file systems; starting with versions 3.1, NT could be installed on or file systems.
Windows NT introduced its own driver model, the Windows NT driver model, and is incompatible with older driver frameworks. With, the Windows NT driver model was enhanced to become the, which was first introduced with, but was based on the NT driver model.
Added native support for the, which is also available for, and to an extent,. Development. Original Windows NT wordmark Microsoft decided to create a portable operating system, compatible with and and supporting, in October 1988. When development started in November 1989, Windows NT was to be known as 3.0, the third version of the operating system developed jointly by Microsoft and.
To ensure portability, initial development was targeted at the XR, switching to the in late 1989, and then the in 1990. Microsoft also continued parallel development of the DOS-based and less -demanding Windows environment, resulting in the release of in May 1990. Windows 3 was eventually so successful that Microsoft decided to change the primary for the still unreleased NT OS/2 (as it was then known) from an extended OS/2 API to an extended. This decision caused tension between Microsoft and IBM and the collaboration ultimately fell apart. IBM continued OS/2 development alone while Microsoft continued work on the newly renamed Windows NT. Though neither operating system would immediately be as popular as Microsoft's MS-DOS or Windows products, Windows NT would eventually be far more successful than OS/2.
Microsoft hired a group of developers from led by to build Windows NT, and many elements of the design reflect earlier DEC experience with Cutler's and, but also an unreleased object-based operating system developed by Dave Cutler for. The operating system was designed to run on multiple and multiple hardware platforms within each architecture. The platform dependencies are largely hidden from the rest of the system by a kernel mode module called the (Hardware Abstraction Layer).
Windows NT's kernel mode code further distinguishes between the 'kernel', whose primary purpose is to implement processor- and architecture-dependent functions, and the 'executive'. This was designed as a modified, as the Windows NT kernel was influenced by the developed at Carnegie Mellon University, but does not meet all of the criteria of a pure microkernel. Both the kernel and the executive are together into the single loaded module; from outside this module there is little distinction between the kernel and the executive. Routines from each are directly accessible, as for example from kernel-mode device drivers.
API sets in the Windows NT family are implemented as subsystems atop the publicly undocumented; this allowed the late adoption of the Windows API (into the Win32 subsystem). Windows NT was one of the earliest operating systems to use internally. Releases. Lextrait, Vincent (January 2010). Retrieved January 4, 2010. ^ (Press release). October 27, 1998.

WebDAV Buffer Overflow Vulnerability on Windows 2000 & IIS 5 NTDLL.DLL Buffer Overrun Vulnerability Windows 2000 / IIS5 / WebDAV PO Box 395, Holden, MA,01520 Tel: 617-921-5410. Virus/Worm/Trojan Resources Virus Alert Updated NTDLL.DLL Buffer Overrun Vulnerability (MS03-007) on Windows 2000 / IIS5 / WebDAV URL for this article: Version 1.9 (Latest update: 5/13/2003) Author:.
Before we begin: - There is additional information on the Webcast from and. The webcast is archived and is highly recommended if you want to learn more about this vulnerability. Microsoft released an advisory on a very serious vulnerability on Windows 2000 (NTDLL.DLL) on March 17, 2003 and it was classified as a CRITICAL vulnerability.
As of March 25, 2003, we know of many DLLs associated with NTDLL.DLL, and therefore, it is critical for system owners to fix this vulnerability as soon as possible. Updated on 4/23/2003 from Microsoft: Windows NT 4.0 also contains the underlying vulnerability in ntdll.dll, however it does not support WebDAV and therefore the known exploit was not effective against Windows NT 4.0. Microsoft has now released a patch for Windows NT 4.0.
Severity Rating: (from Microsoft security advisory MS03-007) Windows NT 4.0 Important Windows NT 4.0 Terminal Server Edition Important Windows 2000 Critical Note: The are the only ways to completely fix this vulnerability. Note: There is a significant risk of exposure to this vulnerability because it is directly associated with the WebDAV component of IIS5, which is included and enabled by default when installing Windows 2000 servers. Un-patched IIS 5 servers with WebDAV enabled that are connected to the Internet would allow anyone to exploit this vulnerability via HTTP ports. Since there are a huge number of IIS servers installed around the world, this could potentially be one of the most serious and most widespread problems. There have been many great discussions about this WebDAV buffer overflow vulnerability. Even though there are many workarounds provided by Microsoft, the patch from Microsoft is still the only way to protect your system from this vulnerability.
KLC CONSULTING strongly advises system owners to apply this patch as soon as possible, HOWEVER, make sure you evaluate the patch in a test environment first, before applying it to your production environment. Planning a patch process for this vulnerability is extremely critical because the exploits have been publicly available. In this article, we include 2 versions of publicly available exploits, and in the Exploit Analysis section, we include a paper demonstrating these exploits. There are significant concerns that these zero-day exploits might have been tested underground for quite some time. We know for a fact that an exploit of this vulnerability has been used to successfully hack an Army web server on March 11, 2003, a week before Microsoft released the security advisory. The rumors on the street expect a worm with a WebDAV exploit to spread within the next few weeks or months. As we do not like to speculate on rumors, there is a substantial amount of chatter on the Internet concerning large exploits that are likely take place.
Technical description from: 'Microsoft Windows 2000 supports the World Wide Web Distributed Authoring and Versioning (WebDAV) protocol., defined in RFC 2518, is a set of extensions to the Hyper Text Transfer Protocol (HTTP) that provide a standard for editing and file management between computers on the Internet. A security vulnerability is present in a Windows component used by WebDAV, and results because the component contains an unchecked buffer. An attacker could exploit the vulnerability by sending a specially formed HTTP request to a machine running Internet Information Server (IIS). The request could cause the server to fail or to execute code of the attacker’s choice. The code would run in the security context of the IIS service (which, by default, runs in the LocalSystem context). Although Microsoft has supplied a patch for this vulnerability and recommends all affected customers install the patch immediately, additional tools and preventive measures have been provided that customers can use to block the exploitation of this vulnerability while they are assessing the impact and compatibility of the patch.
These temporary workarounds and tools are discussed in the “Workarounds” section in the FAQ below. Is actually found on NT 3.51, NT 4.0, W2K and XP, but only the version in Windows 2000 is vulnerable.' Through the author’s exposure to various aspects on this topic and wide range of research analysis (,) applying the seems to be the ONLY way to truly protect yourself from WebDAV exploit attacks. However, before you apply this patch to any systems, make sure you understand the caveats to the. Read the following section before applying this patch to save yourself from major problems.
The following 'caveats' are from the ' Additional information about this patch' section of. Caveats: If you are running Windows 2000 SP2, before installing this patch please check the version of ntoskrnl.exe on your system. To verify the version of ntoskrnl.exe on your system, perform the following steps: 1. Browse to the%windir% system32 directory 2. Right-click ntoskrnl.exe 3.
Choose properties. The version information is located on the ‘version’ tab. Versions of ntoskrnl.exe between 5.0.2195.4797 and 5.0.2195.4928 (inclusive) are not compatible with this patch. These versions were only distributed with Product Support Services hotfixes. If the patch for this issue is installed on a system with one of these versions of ntoskrnl.exe, the machine will fail on the first reboot with a Stop 0x00000071 message and will have to be recovered using the Windows 2000 recovery console and the backup copy of ntdll.dll stored in the “ winnt $NTUninstallQ815021$” directory. To update a system with a version of ntoskrnl.exe distributed from Product Support Services, you must first contact PSS before applying this patch. Information on contacting Product Support Services can be found at: Alternatively you can upgrade to SP3 prior to installing this patch.
