  • All of a sudden my Windows 7 x64 computer is unable to connect to random Windows 2008 R2 servers via Remote Desktop.

    I can connect to the same servers from other Windows 7 machines.

    The only fix I’ve come across so far is this, except that key doesn’t exist on either my machine or on the server(s):

    To resolve this issue, follow these steps:

    1. Start Registry Editor.
    2. Locate and then click the following registry subkey:

      HKEY_LOCAL_MACHINESystemCurrentControlSetServicesTermServiceParameters

    3. Under this registry subkey, delete the following values:
      • Certificate
      • X509 Certificate
      • X509 Certificate ID
    4. Quit Registry Editor, and then restart the server.

    Does anyone have any suggestions please as I’m at a total loss what is happening here.

    Thanks.

  • Hi,

    You can try to configure the target server NIC properties to see whether solve this issue.

    Local Area Connection -> Properties -> Configure -> Advanced -> IPv4 Large Send Offload =Disabled.

    If it doesn’t solve this issue, you can open the regedit.exe on target server, and navigate to:

    HKEY_LOCAL_MACHINESYSTEMCurrentControlSetServicesTermServiceParameters

    After exporting this for safekeeping, then you can delete the Certificate keys. Reboot the target server to see whether the same issue still exists.

Добрый день! Уважаемые читатели и гости IT блога Pyatilistnik.org. В прошлый раз мы с вами успешно устранили ошибку «This coild be to CredSSP encryption oracle remediation» при попытке подключения к RDS ферме. Сегодня мы рассмотрим ситуацию так же при работе с ним, а именно разрыв подключения с ошибкой «Этот сеанс будет прекращен из-за ошибки шифрования данных«. Давайте смотреть в чем дело и как это можно обойти, я опишу 8 быстрых методов.

Описание ошибки шифрования при подключении к RDS ферме

Как я много раз рассказывал у меня в компании есть несколько больших RDS ферм от 50 RDSH хостов, где работают свыше 1000 пользователей одновременно. Начиная с конца октября стали появляться случаи с обрывами соединений вот с такой формулировкой:

Этот сеанс будет прекращен из-за ошибки шифрования данных. Попробуйте подключиться заново к удаленному компьютеру (This session will be terminated due to a data encryption error. Try reconnecting to the remote computer)

Этот сеанс будет прекращен из-за ошибки шифрования данных.

Разрывы были через каждые минут 15-20. Данная проблема при чем была, только у пользователей кто при подключении использовал корпоративный VPN и уже потом шли работать на терминальную ферму.

Диагностика и устранение проблемы

Сразу скажу, что данная проблема исключительно на стороне клиентской операционной системы, так как исследовав более 6 случаев, я ничего подозрительного не обнаружил на брокерах подключений или на самих RDSH хостах, у которых данный пользователь числился как disconnected.

  • 1️⃣Первое, что вы должны сделать, это определить версию вашей операционной системы, так как от этой информации зависит, находится она на поддержке или нет
  • 2️⃣Если ваша ОС поддерживается Microsoft, то вам срочно необходимо установить все доступные обновления безопасности, так и дополнительные. Для этого нажмите одновременно клавиши WIN и I, чтобы вызвать окно «Параметры Windows«. Далее найдите раздел «Обновление и безопасность«.

Обновление Windows

Обязательно перейдите в дополнительные параметры.

Дополнительные параметры обновления Windows

И удостоверьтесь, что у вас активирован пункт «При обновлении Windows получать обновления для других продуктов Майкрософт«.

При обновлении Windows получать обновления для других продуктов Майкрософт

После этого нажмите назад, чтобы вернуться на основное окно установки обновлений. Нажмите кнопку «Проверить наличие обновлений» если у вас WSUS, или же пункт «Проверять наличие обновлений из Центра обновления Майкрософт в Интернете«

Проверять наличие обновлений из Центра обновления Майкрософт в Интернете

Начнется проверка обновлений, если что-то будет найдено, то нужно обязательно установить. После установки обязательно перезагрузите компьютер.

Скачивание обновлений Windows 10

  • 3️⃣Если это не помогло и все так же получаете разрывы соединений, то пробуем обновить версию RDP клиента если она не последняя. Для этого перейдите в каталог:

Там нужно найти файл mstsc.exe и вызвать его свойства. На вкладке «Подробно» посмотрите версию файла. Удостовериться, что она свежая, это можно понять по дате изменения.

Версия mstsc

  • 4️⃣Попробуйте отключить на сетевой карте параметр «Large Send Offload (IPv4)«.Параметр «Large Send Offload (IPv4)» отвечает, за то чтобы фрагментацией сетевых пакетов занималась сетевая карта, CPU. Следовательно, небольшая часть нагрузки с Windows будет перенесена на сетевой адаптер.

Откройте диспетчер устройств, через правый клик по кнопке «Пуск».

Открываем диспетчер устройств

Далее находим сетевые адаптеры. Тут выберите нужный адаптер, если их несколько. Переходим в его свойства, вкладка «Дополнительно«. Находим в списке пункт «Large Send Offload (IPv4)» и меняем его значение на «Disable«. Применяем настройки и перезагружаем систему.

Еще пишут, что можно удалить службу Citrix DNE Lightweight Filte с сетевого адаптера или basic filtration module (net stop bfe). Кто-то переустановил протоколы Link-Layer Topology (Mapper I/O Driver and Responder), а также службу QoS Packet Scheduler, потом перезагрузка

Large Send Offload (IPv4)

    • 5️⃣Еще как вариант решения проблемы, это смена RDP клиента, например на Remote Desktop Connection Manager или можно попробовать установить «Удаленный рабочий стол» из магазина.
    • 6️⃣В старых версиях Windows, например в Windows 7, можно было попробовать удалить содержимое куста реестра:

HKEY_LOCAL_MACHINESYSTEMCurrentControlSetServices TermServiceParameters

Там если есть записи: Certificate, X509 Certificate,X509 Certificate ID, то их нужно удалить, НО обязательно перед этим экспортируйте данный куст реестра, чтобы можно было его восстановить в случае чего.

HKEY_LOCAL_MACHINESYSTEMCurrentControlSetServicesTermServiceParameters

  • 7️⃣Еще очень важно проверить, что у вас ошибку «Этот сеанс будет прекращен из-за ошибки шифрования данных. Попробуйте подключиться заново к удаленному компьютеру» не вызывает какое-то VPN ПО или Proxy ПО. Обязательно проверьте нет ли у вас «Sonicwall Global VPN» и его аналогов, возможно VNC. Выведите список установленных программ в Windows и изучите их.
  • 8️⃣Дополнительно изучите журналы Windows.
  1. %SystemRoot%System32WinevtLogsApplication.evtx
  2. %SystemRoot%System32WinevtLogsSystem.evtx
  3. %SystemRoot%System32WinevtLogsMicrosoft-Windows-RemoteDesktopServices-SessionServices%4Operational.evtx
  4. %SystemRoot%System32WinevtLogsMicrosoft-Windows-TerminalServices-LocalSessionManager%4Admin.evtx
  5. %SystemRoot%System32WinevtLogsMicrosoft-Windows-TerminalServices-LocalSessionManager%4Operational.evtx
  6. %SystemRoot%System32WinevtLogsMicrosoft-Windows-TerminalServices-RemoteConnectionManager%4Admin.evtx
  7. %SystemRoot%System32WinevtLogsMicrosoft-Windows-TerminalServices-RemoteConnectionManager%4Operational.evtx
  • 9️⃣Так же посмотрите нет ли случайно ошибок на стороне антивируса, возможно он как-то может  мешать нормальной работе.

На этом у меня все, надеюсь, что вы смогли решить свою проблему с RDP подключением. С вами был Иван Сёмин, автор и создатель IT портала Pyatilistnik.org.

Если во время работы с удаленным рабочим столом (в том числе — на сервере терминалов или RemoteApp) пользователей выкидывает с обрывом связи с ошибкой «Этот сеанс будет прекращен из-за ошибки шифрования данных.» или «Because of an error in data encryption, this session will end.» — то, очевидно, происходит нарушение целостности шифрования.

Нарушение это, как правило, происходит по причине косяков сети. Причем косяки могут быть как на стороне клиента (если выкидывает конкретного человека), так и на стороне сервера или маршрутизаторов / коммутаторов (если выкидывает периодически то того пользователя, то этого).

Здесь собраны несколько советов — как можно поправить ситуацию. Это решения, используемые разными людьми, в том числе — и мной лично. Кому-то помогало одно, кому-то — другое.

Windows: ошибка Этот сеанс будет прекращен из-за ошибки шифрования данных в терминальной сессии
1) Редактируем реестр клиентского компьютера (regedit).

Идем по адресу:

HKEY_LOCAL_MACHINESystemCurrentControlSetServicesTermServiceParameters

и удаляем там ключи «Certificate», «X509 Certificate», «X509 Certificate ID». После чего перезагружаем компьютер.

Это, кстати, рекомендуемый по данной проблеме вариант Microsoft ( https://support.microsoft.com/ru-ru/help/323497/-the-rdp-protocol-component-data-encryption-detected-an-error…-error-message ).

2) В свойствах сетевой карты на клиенте выставляем значение «Large Send Offload» или «Offload TCP Large Send» в «выключено».

Заходим в «Сетевые соединения», в свойства сетевого соединения, «Дополнительно» и перемещаемся на вкладку дополнительных параметров. Т.е. нам надо попасть в свойства сетевой карты, через которую происходит связь с сервером терминалов.

Если в свойствах есть параметр, который звучит как «Offload TCP Large Send» или «Large Send Offload» или как-то так, и он установлен в некое число — выставляем этот параметр в «Выключено» или «Disabled».

3) В свойствах сетевой карты на клиенте выставляем значение «Offload checksum» в «Выключено» или «Disabled» (если такое свойство есть).

4) Проверьте, что сетевое соединение до сервера терминалов устойчиво и не дает потерь пакетов на пакетах размером с MTU (например, размером 1500 байт ). Из-за сколь-нибудь значимого количества потерь возможны косяки с шифрованием RDP.

5) Как крайний случай — попробывать поменять сетевую карту. Соответственно, у клиента или на сервере — в зависимости — только ли у одного клиента такая байда случается или у нескольких.

Windows

На Windows 11 при подключении к рабочему серверу по RDP через VPN сегодня словил ошибку:

Этот сеанс будет прекращен из-за ошибки шифрования данных. Попробуйте подключиться заново к удаленному компьютеру.

This session will be terminated due to a data encryption error. Try reconnecting to the remote computer.

rdp

После повторного соединения снова выскочила ошибка и соединение RDP завершилось. И так каждые 5-10 минут.

Источник проблем

Погуглил вопрос и вычитал много странного. В первую нужно определить источник проблемы: сервер или клиент. Я параллельно подключился к домашнему серверу по RDP и вскоре получил ту же самую ошибку. Одновременно отвалилось и рабочее подключение и подключение к домашнему серверу. Значит, дело именно в клиенте, т.е. в моём компьютере.

Проверка при подключении к домашнему серверу исключила из источников проблем сеть провайдера, роутер и возможные потери данных, ибо сервер у меня в той же домашней сети что и рабочий ноутбук.

Переключил на ноуте проводную сеть на Wi-Fi и получил ту же ошибку: патчкорд не при чём, сетевая карта тоже.

Решение

Перезагрузил ноутбук, помогло. Вероятно, что-то пошло не так в ОС или работающих службах.

Окончательно вылечил так:

Лечим Windows 11 Pro

Альтернативные решения

Определяем источник проблем: сервер или клиент.

Перезагружаем сервер/клиент. Если не помогает перезагрузка, то устанавливаем последние обновления Windows. На клиенте обновляем клиент RDP до последней версии.

Если обновление не помогло, то пробуем в настройках сетевой карты отключить параметр Large Send Offload (проводное соединение).

win

Для старых версий Windows есть рекомендации от поддержки Microsoft — перейти к ветке реестра:

HKEY_LOCAL_MACHINESYSTEMCurrentControlSetServicesTermServiceParameters

и удалить там ключи «Certificate», «X509 Certificate», «X509 Certificate ID». Предварительно сделайте резервную копию ветки реестра.

Следующий шаг — провести проверку на вирусы, посмотреть, нет ли каких лишних параметров в настройках сетевой карты.

Ещё один вариант решения — обновление драйвера сетевой карты, замена сетевой карты.

  • Подробнее о Настройка зеркалирования в Microsoft SQL Server 2014

Microsoft SQL Server

Зеркалирование или mirroring в MS SQL Server 2014 всё ещё есть. Это очень полезное решение для повышения доступности базы данных. Если ваш сервер упал, посыпались винты, сгорел ЦОД, то возможность быстро переключиться на резервный сервер, не занимаясь восстановлением сервера или БД из бэкапа, экономит кучу времени, денег и нервов. Однако, не следует рассматривать зеркалирование как замену резервному копированию, так как оно не спасает от случайного удаления данных.

Because of an error in data encryption, this session will now end.

This is the error I’ve been getting more and more frequently over the past few days, to the point that I can’t ignore it because it’s happening consistently within 5 minutes of connecting — sometimes within a few seconds. Both the remote and local machines are Windows 7 Pro x64. The remote machine is behind a Linksys RV082, and I’m using UPnP to forward a remote port to the correct local port. This setup had been working fine for several months, and I can’t think of any recent relevant changes that might have been made.

Things I’ve already tried:

  • Disabling unnecessary components of the network connection on the remote machine, until only IPv4 and Client for Microsoft Networks remain.
  • Disabling TCP large send offload on both the remote and local machines.
  • Confirming that the remote machine is not mentioned anywhere in any DMZ settings on the Linksys router.
  • Confirming that there are no x509-related registry keys screwing things up (this is the suggested fix for a slightly different error anyway).

These are the only solutions I’ve been able to find after about an hour of searching, and most of them apply to XP or Server 2003 in any case. If anyone could suggest something else, it would be much appreciated.

I have been researching this as well and I feel like I went down the same road is you since every fix applies to vista/xp. However on Microsoft Technet I found someone who fixed this by deleting the certificate then reconnecting:

I just came across this error myself. I was attempting to remote desktop in from one XP machine >to another. To fix, I went into the Registry:

HKEY_LOCAL_MACHINESYSTEMCurrentControlSetServicesTermServiceParameters

After exporting this for safekeeping, I deleted the Certificate keys. I restarted the target PC >and was able to successfully connect. I can only surmise that the problem is a corrupted >certificate or something. Deleting the certificate stored in the registry seems to have reset it. >The certificate key is different from the previous one, so maybe the target PC’s certificate >expired?

Mostly just guesswork here, but this solution worked for me!

It may not be a definitive fix since this issue seems so random because it worked for months before now but I figured it’s worth a shot for you to try.

Update

Try deleting the string value for the machine you are trying to connect to under:HKEY_CURRENT_USERSoftwareMicrosoftTerminal Server ClientDefault

Let me know how it goes I’ll check back when I get to my hotel after dinner.

I had the same problem connectring Windows 7 to Windows 2008R2 server over rdp. I just did a clean install of my computer and it is simply not possible to connect over rdp. After removing Microsoft Sequrity Essesials and instead installing Symantec Endpoint Protection 12.1.2015 everything works just fine.

Had the same issue on my desktop, so: on the client side. For me the following solved the problem:

  • Removed the Citrix DNE Lightweight Filter
  • Removed the Virtual Machine Network Services
  • Removed the Virtual PC Network Filter service

I had this issue, I gave up and I Re-Installed W7 on my Dell and RDP worked, only after copying my documents back did it fail again,

What I found was that I had copied the default.rdp file from the old PC and replaced the one on the new PC with it.

I Re-Installed W7 again and then this time didn’t copy the default.rdp file over and the PC and RDP works perfectly. (I suppose system restore to a time when it was working could also work,)

After weeks of hunting this was the problem. 1 small file change.
