摘要Summary

本文說明如何在 SMB 用戶端和伺服器元件上啟用和停用伺服器訊息區（SMB）第1版（SMBv1）、SMB 版本2（SMBv2）和 SMB 第3版（SMBv3）。This article describes how to enable and disable Server Message Block (SMB) version 1 (SMBv1), SMB version 2 (SMBv2), and SMB version 3 (SMBv3) on the SMB client and server components. 

在 Windows 7 和 Windows Server 2008 R2 中，停用 SMBv2 會停用下列功能：In Windows 7 and Windows Server 2008 R2, disabling SMBv2 deactivates the following functionality:

• 要求複利-允許以單一網路要求傳送多個 SMB 2 要求Request compounding - allows for sending multiple SMB 2 requests as a single network request
• 較大的讀取和寫入-更有效率地使用更快速的網路Larger reads and writes - better use of faster networks
• 資料夾和檔案屬性的快取-用戶端保留資料夾和檔案的本機複本Caching of folder and file properties - clients keep local copies of folders and files
• 持久的控制碼-允許連接在暫時中斷連線時，以透明的方式重新連線到伺服器Durable handles - allow for connection to transparently reconnect to the server if there is a temporary disconnection
• 改良的訊息簽署-HMAC SHA-256 將 MD5 取代為雜湊演算法Improved message signing - HMAC SHA-256 replaces MD5 as hashing algorithm
• 增強檔案共用的擴充性-每台伺服器的使用者、共用和開啟檔案數目大幅增加Improved scalability for file sharing - number of users, shares, and open files per server greatly increased
• 符號連結的支援Support for symbolic links
• 用戶端 oplock 租用模型-限制用戶端與伺服器之間傳輸的資料，改善高延遲網路的效能並增加 SMB 伺服器的擴充性Client oplock leasing model - limits the data transferred between the client and server, improving performance on high-latency networks and increasing SMB server scalability
• 大型 MTU 支援-適用于 10 gigabye （GB） Ethernet 的完整使用Large MTU support - for full use of 10-gigabye (GB) Ethernet
• 改良的能源效率-已開啟伺服器的用戶端可以進入睡眠狀態Improved energy efficiency - clients that have open files to a server can sleep

在 Windows 8、Windows 8.1、Windows 10、Windows Server 2012、Windows Server 2012 R2、Windows Server 2016 和 Windows Server 2019 中，停用 SMBv3 會停用下列功能（以及前述清單中所述的 SMBv2 功能）：In Windows 8, Windows 8.1, Windows 10, Windows Server 2012, Windows Server 2012 R2, Windows Server 2016, and Windows Server 2019, disabling SMBv3 deactivates the following functionality (and also the SMBv2 functionality that's described in the previous list):

• 透明容錯移轉-在維護或容錯移轉期間，用戶端不會中斷叢集節點的重新連線Transparent Failover - clients reconnect without interruption to cluster nodes during maintenance or failover
• Scale Out –所有檔案叢集節點上共用資料的平行存取Scale Out – concurrent access to shared data on all file cluster nodes 
• 多重通道-當用戶端與伺服器之間有多個路徑可用時，網路頻寬和容錯的匯總Multichannel - aggregation of network bandwidth and fault tolerance if multiple paths are available between client and server
• SMB 直接傳輸-新增 RDMA 網路支援以提供非常高效能，並具有低延遲和低 CPU 使用率SMB Direct – adds RDMA networking support for very high performance, with low latency and low CPU utilization
• 加密–提供端對端加密，並保護不受信任網路上的竊聽Encryption – Provides end-to-end encryption and protects from eavesdropping on untrustworthy networks
• 目錄租用-透過快取改善分公司中的應用程式回應時間Directory Leasing - Improves application response times in branch offices through caching
• 效能優化-針對小型隨機讀取/寫入 i/o 的優化Performance Optimizations - optimizations for small random read/write I/O

使用群組原則停用 SMBv1 伺服器Disable SMBv1 Server with Group Policy

此程式會在登錄中設定下列新專案：This procedure configures the following new item in the registry:

HKEY_LOCAL_MACHINE \SYSTEM\CurrentControlSet\Services\LanmanServer\ParametersHKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\LanmanServer\Parameters

• 登錄專案： SMB1Registry entry: SMB1
• REG_DWORD： 0 = 已停用REG_DWORD: 0 = Disabled

若要使用群組原則來進行此設定，請遵循下列步驟：To configure this by using Group Policy, follow these steps:

1. 開啟 [群組原則管理主控台]****。Open the Group Policy Management Console. 在應包含新的喜好設定項目之群組原則物件 (GPO) 上按一下滑鼠右鍵，然後按一下 [編輯]****。Right-click the Group Policy object (GPO) that should contain the new preference item, and then click Edit.

2. 在 [電腦設定] 底下的主控台樹中，展開 [喜好設定] 資料夾，然後展開 [ Windows 設定] 資料夾。In the console tree under Computer Configuration, expand the Preferences folder, and then expand the Windows Settings folder.

3. 以滑鼠右鍵按一下 [登錄] 節點，指向 [新增]，然後選取 [登錄專案]。Right-click the Registry node, point to New, and select Registry Item.

   

在 [新增登錄內容] 對話方塊中，選取下列各項：In the New Registry Propertiesdialog box, select the following:

• 動作：建立Action: Create
• Hive： HKEY_LOCAL_MACHINEHive: HKEY_LOCAL_MACHINE
• 金鑰路徑： SYSTEM\CurrentControlSet\Services\LanmanServer\ParametersKey Path: SYSTEM\CurrentControlSet\Services\LanmanServer\Parameters
• 值名稱： SMB1Value name: SMB1
• 數值型別： REG_DWORDValue type: REG_DWORD
• 數值資料：0Value data: 0

這會停用 SMBv1 伺服器元件。This disables the SMBv1 Server components. 此群組原則必須套用至網域中所有必要的工作站、伺服器和網域控制站。This Group Policy must be applied to all necessary workstations, servers, and domain controllers in the domain.

使用群組原則停用 SMBv1 用戶端Disable SMBv1 Client with Group Policy

若要停用 SMBv1 用戶端，必須更新服務登錄機碼，以停用MRxSMB10的開頭，然後必須從LanmanWorkstation的專案中移除對MRxSMB10的相依性，讓它可以正常啟動，而不需要先啟動MRxSMB10 。To disable the SMBv1 client, the services registry key needs to be updated to disable the start of MRxSMB10 and then the dependency on MRxSMB10 needs to be removed from the entry for LanmanWorkstation so that it can start normally without requiring MRxSMB10 to first start.

這會更新並取代登錄中下列2個專案的預設值：This will update and replace the default values in the following 2 items in the registry:

HKEY_LOCAL_MACHINE \SYSTEM\CurrentControlSet\services\mrxsmb10HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\mrxsmb10

登錄專案：啟動REG_DWORD： 4= 已停用Registry entry: Start REG_DWORD: 4= Disabled

HKEY_LOCAL_MACHINE \SYSTEM\CurrentControlSet\Services\LanmanWorkstationHKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\LanmanWorkstation

登錄專案： DependOnService REG_MULTI_SZ： "Bowser"、"MRxSmb20"、"NSI"Registry entry: DependOnService REG_MULTI_SZ: "Bowser","MRxSmb20″,"NSI"

若要使用群組原則來進行此設定，請遵循下列步驟：To configure this by using Group Policy, follow these steps:

1. 開啟 [群組原則管理主控台]****。Open the Group Policy Management Console. 在應包含新的喜好設定項目之群組原則物件 (GPO) 上按一下滑鼠右鍵，然後按一下 [編輯]****。Right-click the Group Policy object (GPO) that should contain the new preference item, and then click Edit.

2. 在 [電腦設定] 底下的主控台樹中，展開 [喜好設定] 資料夾，然後展開 [ Windows 設定] 資料夾。In the console tree under Computer Configuration, expand the Preferences folder, and then expand the Windows Settings folder.

3. 以滑鼠右鍵按一下 [登錄] 節點，指向 [新增]，然後選取 [登錄專案]。Right-click the Registry node, point to New, and select Registry Item.

4. 在 [新增登錄內容] 對話方塊中，選取下列各項：In the New Registry Properties dialog box, select the following:

   • 動作：更新Action: Update
   • Hive： HKEY_LOCAL_MACHINEHive: HKEY_LOCAL_MACHINE
   • 金鑰路徑： SYSTEM\CurrentControlSet\services\mrxsmb10Key Path: SYSTEM\CurrentControlSet\services\mrxsmb10
   • 值名稱： StartValue name: Start
   • 數值型別： REG_DWORDValue type: REG_DWORD
   • 數值資料：4Value data: 4

   

5. 然後移除剛停用之MRxSMB10的相依性。Then remove the dependency on the MRxSMB10 that was just disabled.

   在 [新增登錄內容] 對話方塊中，選取下列各項：In the New Registry Properties dialog box, select the following:

   • 動作：取代Action: Replace
   • Hive： HKEY_LOCAL_MACHINEHive: HKEY_LOCAL_MACHINE
   • 金鑰路徑： SYSTEM\CurrentControlSet\Services\LanmanWorkstationKey Path: SYSTEM\CurrentControlSet\Services\LanmanWorkstation
   • 值名稱： DependOnServiceValue name: DependOnService
   • 數值型別： REG_MULTI_SZValue type: REG_MULTI_SZ
   • 數值資料：Value data:
     • BowserBowser
     • MRxSmb20MRxSmb20
     • NSINSI

   注意

   這三個字串不會有專案符號（請參閱下列螢幕擷取畫面）。These three strings will not have bullets (see the following screen shot).

   

   預設值包含許多 Windows 版本中的MRxSMB10 ，因此藉由使用這個多重值字串來取代它們，它實際上是將MRxSMB10移除為LanmanServer的相依性，並從四個預設值減少為上述三個值。The default value includes MRxSMB10 in many versions of Windows, so by replacing them with this multi-value string, it is in effect removing MRxSMB10 as a dependency for LanmanServer and going from four default values down to just these three values above.

   注意

   當您使用群組原則管理主控台時，不需要使用引號或逗號。When you use Group Policy Management Console, you don't have to use quotation marks or commas. 只要在個別行上輸入每個專案。Just type the each entry on individual lines.

6. 重新開機目標系統，以完成 SMB v1 的停用。Restart the targeted systems to finish disabling SMB v1.

摘要Summary

如果所有設定都位於相同的群組原則物件（GPO）中，群組原則管理會顯示下列設定。If all the settings are in the same Group Policy Object (GPO), Group Policy Management displays the following settings.

測試和驗證Testing and validation

這些設定完成後，允許原則進行複寫和更新。After these are configured, allow the policy to replicate and update. 如需測試，請在命令提示字元中執行gpupdate/force ，然後檢查目的電腦，以確保正確套用登錄設定。As necessary for testing, run gpupdate /force at a command prompt, and then review the target computers to make sure that the registry settings are applied correctly. 請確定 SMB v2 和 SMB v3 適用于環境中的所有其他系統。Make sure SMB v2 and SMB v3 is functioning for all other systems in the environment.
