Case #3: Autopilot — Preparing your device for mobile management (0x800705b4)

Symptoms

When enterprise IT administrators use Windows Autopilot to deploy new devices, the «Preparing your device for mobile management (0x800705b4)» error usually pops up in the following stages:

During the OOBE (out-of-box experience), when the device tries to connect to Azure AD for registration, the progress bar will stagnate and eventually an error prompt window will pop up.

The device is stuck in the «Preparing device» interface for a long time (usually more than 30 minutes), and finally displays the error code 0x800705b4, which may also be accompanied by an auxiliary prompt of «Unable to connect to organizational resources». If you check the event viewer, you will see «DeviceEnrollment» related records.

This error usually causes the device to fail to complete the automatic configuration or the enterprise policy and application cannot be deployed normally, and manual intervention is required to continue the setup process.

Картинка с сайта: www.diskgenius.com

Common causes

According to Microsoft official documents and statistical analysis of hundreds of enterprise deployment cases, this error mainly comes from the following aspects:

Network connection problems (65% of cases): The outbound interception rules of the enterprise firewall are too strict, blocking the necessary Azure AD connection; the proxy server is improperly configured, and the special proxy rules required for Autopilot are not correctly configured; the internal DNS server cannot correctly resolve key domain names; port 443 is accidentally closed or restricted

System time is not synchronized (20% of cases): CMOS battery failure causes BIOS time reset and serious system time deviation; NTP server is unreachable, causing the device to be unable to synchronize with the time server; wrong time zone setting, especially international version devices purchased by multinational companies.

Configuration policy problems (10% of cases): Autopilot configuration file errors, for example, there are conflicting settings in the deployment policy; the registration timeout setting is too short, and the default value cannot adapt to the high-latency network environment; the device hash is not pre-registered, and the new device is not correctly imported into the Autopilot device list.

Other system problems (5% of cases): Windows image is damaged, especially custom deployment images; network drivers of specific hardware manufacturers have problems; local system key services are not running properly.

Windows Autopilot greatly simplifies the deployment process of new devices, but many IT administrators will feel troubled when encountering the «Preparing your device for mobile management (0x800705b4)» error. Below I will introduce several proven solutions in detail to help you solve this problem completely.

Method 1. Comprehensive network connection inspection and repair

Step 1. Perform basic network tests. Connect the device to a mobile hotspot or other unrestricted network, then open the command prompt (administrator) and execute the following commands in sequence. This will help check whether they can be pinged normally and whether the delay is within a reasonable range.

ping login.microsoftonline.com
ping enterpriseenrollment.manage.microsoft.com
ping enterpriseenrollment-s.manage.microsoft.com

Step 2. Test the port connectivity.

Use telnet to test port 443: telnet login.microsoftonline.com 443

If there is no telnet client, you can test it through PowerShell: Test-NetConnection -ComputerName login.microsoftonline.com -Port 443

Step 3. Check whether the proxy server is normal. First, open «Settings» — «Network and Internet» — «Proxy»; then, temporarily turn off the «Use a proxy server» option; try Autopilot registration again.

Step 4. Adjust firewall rules. Open Windows Defender Firewall with Advanced Security and create a new outbound rule to allow connections from the following endpoints. Restart the device after applying the rule.

*.manage.microsoft.com
*.microsoftonline.com

Method 2. Accurately synchronize the system time.

Step 1. Perform basic time synchronization. Open the command prompt as an administrator, and then execute the following commands to force time synchronization:

net stop w32time
w32tm /unregister
w32tm /register
net start w32time
w32tm /resync

Step 2. Check the NTP server configuration.

• Check the current time server configuration: w32tm /query /configuration
• If you need to modify the NTP server: w32tm /config /syncfromflags:manual /manualpeerlist:»time.windows.com,0x8″

Step 3. Verify the time zone. Open «Settings» — «Time and Language» — «Date and Time», and make sure «Set time automatically» and «Set time zone automatically» are both turned on. In addition, you need to manually check whether the time zone matches the actual location.

Method 3. Registry Adjustment to Extend Timeout

Step 1. Back up the current registry. Open the Registry Editor (regedit) and navigate to the path below. Right-click «Export» to back up the current branch.

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion

Step 2. Create timeout settings. Create a new item «CDJ» under CurrentVersion (if it does not exist), and then create a new DWORD (32-bit) value in the CDJ item and name it «AADJTimeoutInMinutes». Double-click the newly created value and change the value data to 60 (decimal); finally, restart the device for the change to take effect.

Method 4. Complete System Reset and Redeployment.

Step 1. Prepare the installation media. Download the latest Windows image from Microsoft’s official website, make a bootable USB drive, and select the GPT partition scheme.

Step 2. Install the system completely. Boot from the USB drive, press Shift+F10 on the installation interface to open the command prompt, and enter the following command to skip the network connection. Connect to the network after completing the basic installation.

OOBE\BYPASSNRO

Step 3. Re-register Autopilot. After entering the system, connect to the enterprise network, open «Settings» — «Accounts» — «Work or school account», and then select «Sign in only on this device» to start the registration process.

Method 5. Collect logs and analyze them.

Step 1. Collect necessary logs: open the Event Viewer and export the these logs:

Application and Service Logs/Microsoft/Windows/DeviceManagement-Enterprise-Diagnostics-Provider
Windows Logs/System

Step 2. Look for Autopilot specific logs by navigating to the path: %windir%\debug\microsoft\windows\provisioning\autopilot, and then copy all *.log files.

Step 3. Log in to the Microsoft 365 Administrator Center, create a new service request, and upload all collected logs. Provide a detailed description of the error and the solutions you have tried.

Case #4: 0x800705b4 SCCM – This operation returned because the timeout period expired. Error code: -2147023436 (0x800705b4)

The problem

When you encounter the error «This operation returned because the timeout period expired. Error code: -2147023436 (0x800705b4)» while using System Center Configuration Manager (SCCM), it means that an operation was forced to terminate because the preset waiting time exceeded. This error may occur in a variety of SCCM operation scenarios, including but not limited to key management tasks such as software deployment, policy updates, client installation, and inventory collection. The 0x800705b4 error usually exhibits the following typical symptoms:

Client communication failure: The SCCM client cannot establish an effective connection with the management point (MP) or distribution point (DP), especially in large enterprise environments.

Software deployment interruption: The application or update package suddenly stops during the deployment process, and a timeout error is recorded in the log.

Policy retrieval problem: The client cannot obtain the latest management policy in time, resulting in inconsistent configuration.

Inventory collection delay: Hardware or software inventory data cannot be uploaded to the site server on time.

Specific manifestations in the error log: «Failed to get DP locations» and other similar entries appear in the client log (such as LocationServices.log); the CCMExec service may report an operation timeout; client request processing delays are recorded in the management point log.

Common causes:

After analyzing a large number of enterprise cases, we found that the main causes of the 0x800705b4 error include:

Network-related issues (45% of cases): high network latency, such as the network latency between the client and the SCCM server exceeding the operating threshold; bandwidth restrictions or traffic shaping policies on key network links; intermediate firewalls interrupting long-term connections; DNS resolution delays, slow response of name resolution services.

Server performance issues (30% of cases): SCCM server load is too high, CPU or memory resources are insufficient; disk I/O bottlenecks, slow response of database or distribution point storage; SQL Server performance issues, query execution timeout.

Configuration issues (20% of cases): timeout settings are too short, the default timeout value is not suitable for the actual environment; site boundary configuration errors, clients are assigned to inappropriate sites; client settings are not ideal, and parameters such as polling intervals are improperly configured.

Other issues (5% of cases): insufficient client resources, low performance of terminal devices; security software interference, real-time scanning affects communication; WMI is damaged, and there are problems with Windows Management Specifications.

Method 1. Check the network.

Step 1. Perform basic network tests:

First, perform a continuous ping test from the client to the SCCM server for at least 5 minutes to check the average latency and packet loss rate: ping <SCCM server FQDN> -t

Then, test the connectivity of key ports:

Test-NetConnection <SCCM server IP> -Port 80
Test-NetConnection <SCCM server IP> -Port 443

Step 2. Analyze the network path, and you can try two methods:

Perform tracert to determine the network path: tracert <SCCM server FQDN>
Use PathPing to analyze path performance: pathping <SCCM server FQDN>

Step 3. Optimize bandwidth and QoS. Ensure that SCCM traffic has sufficient bandwidth; configure QoS priority for SCCM-related traffic on network devices; consider deploying distribution points (DPs) at remote sites to reduce WAN dependence.

Method 2. Tune server performance

Step 1. SCCM server resource monitoring, you can use Performance Monitor to track key indicators, such as CPU usage, memory availability, disk queue length, and network utilization.

Step 2. Optimize SQL Server.

First, check the maximum memory configuration of SQL Server:

EXEC sp_configure ‘show advanced options’, 1;
RECONFIGURE;
EXEC sp_configure ‘max server memory (MB)’;

Then, optimize the SCCM database index:

USE CM_<site code>
EXEC sp_updatestats;

Step 3. Adjust IIS configuration, including increasing the idle timeout of SCCM-related application pools (for example, adjusting the default 20 minutes to 40-60 minutes); optimize application pool recycling settings.

Method 3. Adjust client communication settings.

Step 1. Adjust the client timeout settings in the client registry. Find CCM in the following path: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\CCM, and then add or modify:

«CcmHttpTimeout»=dword:0000003c (60 seconds)
«CcmHttpsTimeout»=dword:0000003c

Step 2. To modify the client location service timeout, find the path: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\CCM\LocationServices, and then set: «LocationServiceTimeout»=dword:0000003c

Step 3. Modify the client policy through the SCCM console, for example, increase the number of policy request retries (the default 3 times can be increased to 5 times), and extend the policy retrieval timeout.

Method 4. Optimize SCCM site configuration.

Step 1.  Adjust the site system role. First, check the management point load balancing configuration; then, consider adding additional management points for large sites; and optimize the distribution point content distribution strategy.

Step 2. Optimize boundaries and boundary groups. Make sure that all IP ranges are correctly included in the boundary definition; also check the boundary group and site allocation relationship; and verify the client automatic site allocation logic.

Step 3. Adjust component configuration, for example, modify the number of SMS_EXECUTIVE component threads, adjust the distribution manager (DistMgr) concurrency settings, and optimize software distribution component parameters.

Одной из наиболее часто встречающихся проблем, с которой сталкиваются пользователи Windows при попытке обновить операционную систему, является ошибка 0x800705b4. Она может возникать на разных этапах обновления, мешая пользователю получать последние исправления безопасности и улучшения функционала системы.

В этой статье мы рассмотрим основные причины возникновения ошибки 0x800705b4 и предложим несколько проверенных способов её устранения.

Ошибка 0x800705b4 в Windows обычно возникает в процессе скачивания или установки обновлений операционной системы. Она может проявляться в разных контекстах, но чаще всего связана с тем, что система не может завершить операцию обновления.

Причиной могут быть различные факторы, включая проблемы с интернет-соединением, повреждённые системные файлы или некорректные настройки безопасности.

• Проблемы с интернет-соединением. Загрузка обновлений требует стабильного и быстрого интернет-соединения. Если соединение нестабильно или слишком медленное, это может привести к сбоям в процессе обновления.
• Повреждения в системных файлах. Если важные системные файлы Windows повреждены, это может повлиять на работу службы обновлений.
• Стороннее ПО. Некоторые сторонние антивирусные программы или брандмауэры могут блокировать процесс обновления.
• Перегрузка системы. Если во время обновления система работает с несколькими ресурсоемкими задачами, это может вызвать ошибку.

Существует несколько эффективных способов устранения ошибки 0x800705b4, начиная со стандартных методов диагностики и заканчивая более сложными шагами. Рассмотрим наиболее распространенные методы.

Прежде всего, всегда стоит начать с перезагрузки компьютера. Это простой, но эффективный способ избавиться от временных сбоев, которые могут мешать процессу обновления. После перезагрузки система может завершить оставшиеся процессы и, возможно, успешно загрузить и установить обновления.

Windows предоставляет встроенное средство для диагностики и устранения проблем с обновлениями. Чтобы воспользоваться им, выполните следующие действия:

Откройте «Параметры» (нажмите Win + I).

Перейдите в раздел «Обновление и безопасность».

Выберите Устранение неполадок, затем кликните «Дополнительные средства устранения неполадок».

Найдите «Windows Update» и нажмите «Запустить средство устранения неполадок».

Это средство выполнит диагностику и попытается устранить выявленные проблемы, которые могут препятствовать нормальной установке обновлений.

Если стандартные методы не помогли, можно вручную сбросить компоненты обновлений Windows. Для этого потребуется несколько команд в командной строке с правами администратора. Вот что нужно сделать:

Откройте командную строку от имени администратора. Для этого нажмите правой кнопкой мыши на кнопку «Пуск» и выберите «Командная строка (Администратор)».

Введите следующие команды по очереди и нажимайте Enter после каждой:

Перезагрузите компьютер и попробуйте снова выполнить обновление.

Эти команды остановят службы обновления, переименуют каталоги: catroot2, SoftwareDistribution, отвечающие за скачивание обновлений, затем перезапустят службы и создадут каталоги снова.

Системные файлы могут быть повреждены, что также является одной из причин возникновения ошибки 0x800705b4. В этом случае помогут встроенные утилиты для восстановления:

Откройте Командную строку от имени администратора.

Введите команду для проверки целостности системных файлов: sfc /scannow

Утилита SFC (Проверка системных файлов) выполнит проверку файлов и восстановит повреждённые.

Если ошибка сохраняется, используйте утилиту DISM (Deployment Imaging Service and Management Tool):

DISM /Online /Cleanup-Image /RestoreHealth

Эта команда поможет восстановить повреждения, связанные с образом системы.

Некоторые сторонние антивирусные программы могут блокировать или препятствовать установке обновлений. Временно отключите антивирус или брандмауэр и попробуйте выполнить обновление ещё раз. Если это помогло, вы можете добавить исключения для Центра обновления Windows в настройках антивируса или обновить сам антивирус до последней версии.

Если ни один из вышеперечисленных способов не помог, можно воспользоваться средством создания установочного носителя от Microsoft. Это позволит загрузить и установить обновление Windows 10 или Windows 11 вручную с помощью установочного носителя — ISO образа операционной системы:

Перейдите на сайт Microsoft чтобы скачать Windows 10 или 11. Скачайте и запустите Средство создания установочного носителя. Следуйте инструкциям по созданию загрузочной флешки или DVD-диска и используйте их для обновления системы.
