DHCP 中的新功能What's New in DHCP

適用於:Windows Server(以每年次管道)、Windows Server 2016Applies To: Windows Server (Semi-Annual Channel), Windows Server 2016

本主題描述新增或變更 Windows Server 2016 中的 「 動態主機設定通訊協定 」 (DHCP) 功能。This topic describes the Dynamic Host Configuration Protocol (DHCP) functionality that is new or changed in Windows Server 2016.

DHCP 是設計用來減少的系統管理負擔和複雜的 TCP 日 IP\ 型網路,例如私人內部網路設定主機網際網路工程設計工作推動 (IETF) 標準。DHCP is an Internet Engineering Task Force (IETF) standard that is designed to reduce the administrative burden and complexity of configuring hosts on a TCP/IP-based network, such as a private intranet. 使用 DHCP 伺服器服務,程序的 TCP/IP 設定戶端 DHCP 會自動執行。By using the DHCP Server service, the process of configuring TCP/IP on DHCP clients is automatic.

下列章節 DHCP 功能提供新功能和變更的相關資訊。The following sections provide information about new features and changes in functionality for DHCP.

DHCP 子網路選取選項DHCP Subnet Selection Options

DHCP 現在支援 (sub-option 5) 118 與 82 選項。DHCP now supports options 118 and 82 (sub-option 5). 您可以使用這些選項來讓您要求的 IP 位址特定子網路,以及從指定 IP 位址和範圍 DHCP proxy 戶端及轉送代理程式。You can use these options to allow DHCP proxy clients and relay agents to request an IP address for a specific subnet, and from a specific IP address range and scope.

如果您使用 DHCP 選項 118,例如執行 Windows Server 2016 和遠端存取伺服器角色 virtual 私人網路 (VPN) 伺服器設定 DHCP proxy client VPN 伺服器可以要求 IP 位址租用 VPN 戶端的特定的 IP 位址。If you are using a DHCP proxy client that is configured with DHCP option 118, such as a virtual private network (VPN) server that is running Windows Server 2016 and the Remote Access server role, the VPN server can request an IP address lease for VPN clients from a specific IP address range.

如果您使用 DHCP 轉送代理 DHCP 選項 82,sub\ 選項 5 設定轉接可以要求 IP 位址租用 DHCP 戶端的特定的 IP 位址。If you are using a DHCP relay agent that is configured with DHCP option 82, sub-option 5, the relay agent can request an IP address lease for DHCP clients from a specific IP address range.

如需詳細資訊,請查看選擇 DHCP 子網路的選項For more information, see DHCP Subnet Selection Options.

新的登入事件 DHCP 伺服器 DNS 登記失敗New Logging Events for DNS Registration Failures by the DHCP Server

DHCP 現在包含登入的環境中 DHCP 伺服器 DNS 使用碼表進行登錄失敗 DNS 伺服器的活動。DHCP now includes logging events for circumstances in which DHCP server DNS record registrations fail on the DNS server.

如需詳細資訊,請查看DHCP 登入事件 DNS 記錄登錄的For more information, see DHCP Logging Events for DNS Record Registrations.

Windows Server 2016 不支援 DHCP NAPDHCP NAP Is Not Supported in Windows Server 2016

網路存取保護 (NAP) 已在 Windows Server 2012 R2 取代和 Windows Server 2016 中 DHCP 伺服器角色不再支援 NAP。Network Access Protection (NAP) is deprecated in Windows Server 2012 R2, and in Windows Server 2016 the DHCP Server role no longer supports NAP. 如需詳細資訊,請查看的功能已經移除或 Deprecated Windows Server 2012 R2 在For more information, see Features Removed or Deprecated in Windows Server 2012 R2.

NAP 支援 DHCP 伺服器角色與 Windows Server 2008、 推出和支援 Windows client 和伺服器作業系統之前的 Windows 10 與 Windows Server 2016。NAP support was introduced to the DHCP Server role with Windows Server 2008, and is supported in Windows client and server operating systems prior to Windows 10 and Windows Server 2016. 下表摘要 NAP 在 Windows Server 的支援。The following table summarizes support for NAP in Windows Server.

作業系統Operating system NAP 支援NAP support
Windows Server 2008Windows Server 2008 支援Supported
Windows Server 2008 R2Windows Server 2008 R2 支援Supported
Windows Server 2012Windows Server 2012 支援Supported
Windows Server 2012 R2Windows Server 2012 R2 支援Supported
Windows Server 2016Windows Server 2016 不支援Not supported

NAP 部署,在執行作業系統,其支援 NAP DHCP 伺服器可以作為 NAP DHCP 執法方法 NAP 執法點。In a NAP deployment, a DHCP server running an operating system that supports NAP can function as a NAP enforcement point for the NAP DHCP enforcement method. 如需 DHCP NAP 中相關資訊,請查看檢查清單︰ 實作 DHCP 執法設計For more information about DHCP in NAP, see Checklist: Implementing a DHCP Enforcement Design.

在 Windows Server 2016 DHCP 伺服器不會執行 NAP 原則,且 DHCP 領域無法 NAP\ 功能。In Windows Server 2016, DHCP servers do not enforce NAP policies, and DHCP scopes cannot be NAP-enabled. 這也是 NAP 戶端 DHCP client 電腦傳送健康 (SoH) DHCP 要求的聲明。DHCP client computers that are also NAP clients send a statement of health (SoH) with the DHCP request. 如果執行 Windows Server 2016 的 DHCP 伺服器,如同任何 SoH 存在於處理這些要求。If the DHCP server is running Windows Server 2016, these requests are processed as if no SoH is present. DHCP 伺服器授與一般 DHCP 租用 client。The DHCP server grants a normal DHCP lease to the client.

如果執行 Windows Server 2016 的伺服器,轉送給支援 NAP 網路原則伺服器 (NPS) 驗證要求 RADIUS proxy,這些 NAP 戶端會評估 NPS 非 NAP\ 處理能力,和 NAP 處理失敗。If servers that are running Windows Server 2016 are RADIUS proxies that forward authentication requests to a Network Policy Server (NPS) that supports NAP, these NAP clients are evaluated by NPS as non NAP-capable, and NAP processing fails.
