Software Update Services for IT Professionals

For general information about Software Update Services, visit the following Microsoft Web site:
Overview of Windows as a service

Windows Update

IT Professionals can use the Windows Update service to configure a server on their corporate network to provide updates to corporate servers and clients. This functionality can be useful in environments where some clients and servers do not have access to the Internet. This functionality can also be useful where the environment is highly managed, and the corporate administrator must test the updates before they are deployed.

Хотфикс: что это такое, для чего используется и как правильно установить?

Многие пользователи компьютеров, работающих под управлением Windows, слышали о таком понятии, как «хотфикс». Что это такое и для чего это нужно, представляет себе далеко не каждый юзер. Однако ничего сложного ни в понимании этого термина, ни в предназначении таких инструментов нет. Далее, как говорится, разложим все по полочкам.

Хотфикс: что это такое?

Для понимания этого термина достаточно просто перевести его английское название. В Windows Hotfix дословно означает «горячее исправление». Иными словами, это есть инструмент быстрого устранения проблем с каким-то отдельно взятым компонентом Windows, если он не работает или функционирует некорректно.

Ситуация, с точки зрения многих пользователей, мягко говоря, забавная. Получается, что разработчики Microsoft выпускают какой-то программный продукт, который гипотетически может давать сбои, а потом начинают быстренько латать в нем дыры, используя для каждого из них хотфикс. Что это? Небрежность при разработке или умышленное действие, приводимое к тому, что пользователя просто заставляют скачивать средства устранения проблем? Думается все-таки второе, поскольку трудно допустить, что в такой уважаемой корпорации работают специалисты, которые не тестируют свои программные продукты на возможное появление ошибок.

Условия установки исправлений

Что же касается установки быстрых исправлений, здесь есть свои подводные камни. Кроме того, что их можно загрузить исключительно с официального сайта Microsoft, сначала необходимо дать запрос, причем по конкретно интересующему пользователя приложению или системному компоненту.

Впрочем, трудностей здесь быть не должно, поскольку прямо на сайте в разделе поддержки нужно выбрать требуемое исправление, указать свою установленную операционную систему и ввести адрес электронной почты. В течение определенного времени придет ответ со ссылкой на загрузку и паролем к архиву (все хотфиксы поставляются исключительно в упакованном виде).

Как установить хотфикс: практические действия

После загрузки архива его необходимо распаковать в любое удобное место, введя для доступа присланный пароль. После разархивирования на жестком диске появится исполняемый файл с номером исправления (так называемый изолированный пакет «Центра обновления»).

Далее все просто. Запускаете файл (желательно сразу использовать старт от имени администратора), соглашаетесь на инсталляцию обновления, дожидаетесь окончания процесса и полностью перегружаете компьютерную систему. По идее, после интеграции обновления приложения или системные компоненты заработают как положено.

Сразу же обратите внимание, что скачивать подобные инструменты с ресурсов, не относящихся к службам поддержки Microsoft, крайне не рекомендуется. И это связано в основном только с тем, что сами архивы или, вложенные в них, апплеты могут содержать вирусные коды, не говоря о том, что вместо хотфикса вам могут подсунуть какое-то другое нежелательное программное обеспечение. Поэтому обращаться следует только к официальному ресурсу.

А проще всего воспользоваться программой Hotfix Downloader, выбрать из списка нужное обновление для своей версии ОС, скачать его и инсталлировать. Так не придется искать хофиксы вручную.

Вместо послесловия

Вот и все, что касается такого понятия, как «хотфикс». Что это такое, думается, уже понятно. Некоторые пользователи, правда, относят сюда еще и утилиты вроде FixIt. В известном смысле эта программа тоже является хотфиксом, правда, изначально предназначена для устранения проблем, связанных исключительно с «Центром обновления» Windows. Для восстановления работоспособности других встроенных приложений и системных служб она не подходит хотя в их неработоспособности «Центр обновления» и может быть виновен, но только косвенно. Впрочем, иногда проблемы могут быть устранены за счет включения автоматического обновления. В таком случае использование хотфиксов может и не потребоваться.

List of currently available hotfixes for the File Services technologies

This article lists the hotfixes that are currently available for users who have installed the File Services technologies on a Windows Server 2012-based computer or a Windows Server 2012 R2-based computer.

Original product version: В Windows 10 — all editions, Windows Server 2012 R2
Original KB number: В 2899011

Summary

File Services provides technologies that help you manage storage, enable file replication, manage shared folders, provide fast file searching, and enable access for UNIX client computers. This article also lists the hotfixes that are currently available for users who use File Services on Windows 8-based computers or Windows 8.1-based computers.

This article contains lists of Microsoft Knowledge Base articles that describe the currently available fixes. The article is divided into two sections. The first section applies to Windows Server 2012 and to Windows 8, and the second section applies to Windows Server 2012 R2 and to Windows 8.1. Each section is divided into subsections for different component drivers: SRV, MRXSMB, and RDBSS. In general, the SRV drivers should be updated on the server or client computer that is hosting the data. The MRXSMB and RDBSS drivers should be updated on the server or client computer that is initiating access to the data. If you are unsure about which component should be updated on which computer, you can update all three component drivers on both the computer that is hosting the data and the computer that is accessing the data.

A servicing approach of installing the monthly rollups provides customers with a consistent model for staying current and secure. You may substitute a more recent monthly rollup in place of an older monthly rollup. The remainders of the updates in this list are still needed as some components in those updates released prior to October 2016 and are not included in a more recent monthly rollup.

Windows Server 2012 and Windows 8

The latest fixes for these SMB components can be achieved by installing two updates:

1. KB 2984005 — September 2014 update rollup for Windows RT, Windows 8, and Windows Server 2012
2. KB 4520007 — October 8, 2019-KB4520007 (Monthly Rollup) or later

Server Message Block (SMB) model

The SMB model consists of two entities: the client and the server.

On the client, applications perform system calls by requesting operations on remote files. These requests are handled by the redirector subsystem ( rdbss.sys ) and by the SMB mini-redirector ( mrxsmb.sys ), both of which translate the requests into SMB protocol sessions and requests over TCP/IP. Starting with Windows Vista, the SMB 2.0 protocol is supported. The mrxsmb10.sys driver handles legacy SMB traffic, and the mrxsmb20.sys driver handles SMB 2.0 and SMB 3.0 traffic.

On the server, SMB connections are accepted, and SMB requests are processed as local file system operations through NTFS and the local storage stack. The srv.sys driver handles legacy SMB traffic, and the srv2.sys driver handles SMB 2.0 traffic. The srvnet.sys component implements the interface between networking and the file server for both SMB protocols. File system metadata and content can be cached in memory via the system cache in the kernel ( ntoskrnl.exe ).

The following screenshot provides an overview of the different layers through which a user request on a client computer must go to perform file operations over the network on a remote SMB file server by using SMB 2.0.

Components in services for NFS in a Windows Server 2012 environment

Services for NFS includes the following components:

This component corresponds to the server-side implementation of the NFS file-sharing protocol. Server for NFS enables a computer that is running Windows Server 2012 or Windows Server 2012 R2 to act as a file server for UNIX-based client computers.

This component corresponds to the client-side implementation of the NFS file-sharing protocol. Client for NFS enables a Windows-based computer that is running Windows Server 2012 (or Windows 8) to access files that are stored on a UNIX-based NFS server.

Windows Server 2012 includes both the Server for NFS and Client for NFS components. However, Windows 8 includes only Client for NFS.

Microsoft Services for NFS provides a file-sharing solution for enterprises that have a mixed Windows and UNIX environment. This communication model consists of client computers and a server. Applications on the client request files that are located on the server through the redirector ( Rdbss.sys ) and NFS mini-redirector ( Nfsrdr.sys ). The mini-redirector uses the NFS protocol to send its request through TCP/IP. The server receives multiple requests from the clients through TCP/IP and routes the requests to the local file system ( Ntfs.sys ), which accesses the storage stack.
