  • Hi

    I require some assistance please.  During the past week I had issues with my NIC’s and Hyper-V machines on my notebook.  This was resolved with the help of the wonderful people in these forums.  I had reset the NIC’s and everything worked
    fine with my virtual machines.

    However after resetting my NIC’s I am unable to use VPN any longer to VPN to some of my clients. In the event viewer I get the the error «RASClient — The error code returned on failure is 720» Event ID 20227. When I try to connect the following
    is displayed «A connection to the remote computer could not be completed. You might need to change the network settings for this connection.»

    I have tried a few things like uninstalling all the WAN Miniports as well as the NIC’s, rebooted the notebook and still no luck. 

    Any help to resolve this will be really appreciated!

Столкнулся со странной ошибкой в Windows 10, когда неожиданно перестали работать все VPN подключения к любым ресурсам с ошибкой:

Не удается подключиться к удаленному компьютеру. Возможно, потребуется изменение сетевых параметров соединение.
Can’t connect to VPN
A connection to the remote computer could not be established. You might need to change the network settings for this connection.

Windows 10 ошибка VPN: Не удается подключиться к удаленному компьютеру. Возможно, потребуется изменение сетевых параметров соединение

Для подключения используется встроенный VPN клиент Windows. С соседнего устройства VPN подключение с такими же настройками работает нормально, т.е. явно проблема не с VPN сервером.

В журнале Application отображается ошибка VPN подключения 720:

EventID: 20227
Source: RasClient
The user dialed a connection named VPN which has failed. The error code returned on failure is 720.

Базовая рекомендации в таких случаях – сбросить настройки стека TCP/IP и параметров сетевых адаптеров компьютера:

netsh winsock reset
netsh int ip reset
ipconfig /release
ipconfig /renew

ipconfig /flushdns

Возможно подключение блокируется правилами Windows Firewall или сторонним антивирусом/брандмауэром (попробуйте временно отключить их).

Проверьте, что в Windows не используется WinHTTP прокси для подключения к интернету.

netsh winhttp show proxy

не используется WinHTTP прокси сервер для подключения к интернету

Current WinHTTP proxy settings:
Direct access (no proxy server).

В данном примере используется прямое подключение.

Если нужно сбросить настройки прокси, выполните:

netsh winhttp reset proxy

Но в моем случае после этого VPN подключения не заработали.

Теперь нужно попробовать переустановить виртуальные адаптеры WAN Miniports в диспетчере устройств

WAN Miniports — виртуальные сетевые адаптеры с драйверами под различные сетевые протоколы подключения. В Windows есть WAN Miniport адаптеры для протоколов IKEv2, IP, IPv6, L2TP, Network Monitor, PPPOE, PPTP, SSTP.

  1. Запустите диспетчер устройств (devmgmt.msc), разверните секцию Network Adapters и удалите все устройства с именем WAN Miniport.
  2. Выберите, например, WAN Miniport (SSTP), щелкаете по нему правой клавишей и выберите Uninstall Device; удалить WAN Miniport адаптеры в диспетчере устройств
  3. Затем переходит к следующему устройству WAN Miniport. Нужно удалить все устройства:
    • WAN Miniport (PPTP)
    • WAN Miniport (PPPOE)
    • WAN Miniport (Network Monitor)
    • WAN Miniport (L2TP)
    • WAN Miniport (IPv6)
    • WAN Miniport (IP)
    • WAN Miniport (IKEv2)
  4. Теперь нужно пересканировать конфигурацию оборудования (Action -> Scan for Hardware changes), и дождаться пока Windows обнаружит и установит драйверы для WAN Miniports устройств. обновить конфигурацию оборудования
  5. После того, как все адаптеры WAN Miniports переустановлены, можете проверить свои VPN подключение. Все должно заработать.

Можно использовать PowerShell для диагностики проблемы с адаптерами WAN Miniports.

Проверьте, что для нужного вам адаптера включены все протоколы (
Enabled=True
), и среди драйверов фильтрации отсутствуют сторонние драйверы (могут быть добавлены антвирусами).

$adapter=Get-NetAdapter -IncludeHidden | Where-Object {$_.InterfaceDescription -eq "WAN Miniport (PPTP)"}
Get-NetAdapterBinding -Name $adapter.name -IncludeHidden –AllBindings

powershell - включить/отключить фильтры драйверов

Можно включить/отключить нужный драйвер так:

Enable-NetAdapterBinding -Name $adapter.name -IncludeHidden -AllBindings -ComponentID ms_wanarp

В Windows 8.1 установка SSTP VPN-подключения завершается ошибкой и сопровождается добавлением в журнал следующего события:

  • источник — RasClient
  • код — 20227
  • описание — пользователь <…> установил удаленное подключение <…>, которое завершилось сбоем. Возвращен код ошибки 720

Причина сбоев — в некорректной работе сетевых устройств (в моем случае в диспетчере устройств в узле «Сетевые адаптеры» как функционирующие неправильно были отмечены: «Мини-порт глобальной сети (IP)», «Мини-порт глобальной сети (IPv6)» и «Мини-порт глобальной сети (Сетевой монитор)»)

Проблема устраняется переустановкой драйверов некорректно работающих устройств следующим образом:

  • нажимаем «Обновить драйверы» — «Выполнить поиск драйверов на этом компьютере» — «Выбрать драйвер из списка уже установленных драйверов»
  • снимаем галочку «Только совместимые устройства»
  • выбираем изготовителя «Microsoft»
  • выбираем драйвер «Сетевой адаптер с отладкой ядра (Майкрософт)»
  • удаляем из списка сетевых адаптеров «Сетевой адаптер с отладкой ядра (Майкрософт)»
  • обновляем конфигурацию оборудования

Замечание 1: без установки «левых» драйверов не получится ни переустановить «родной» драйвер, ни удалить соответствующее устройство

Замечание 2: как я понимаю, в качестве «левого» драйвера можно использовать любой драйвер, использование которого позволит удалить устройство из списка
