若要在命名空間伺服器間維護一致的網域型命名空間,命名空間伺服器必須定期輪詢 Active Directory Domain Services (AD DS) 以取得最新的命名空間資料。To maintain a consistent domain-based namespace across namespace servers, it is necessary for namespace servers to periodically poll Active Directory Domain Services (AD DS) to obtain the most current namespace data.

最佳化命名空間輪詢To optimize namespace polling

使用下列程序來最佳化命名空間輪詢的發生方式:Use the following procedure to optimize how namespace polling occurs:

  1. 按一下 [開始],指向 [系統管理工具],然後按一下 [DFS 管理]Click Start, point to Administrative Tools, and then click DFS Management.

  2. 在主控台樹狀目錄的 [命名空間] 節點下,於網域型命名空間上按一下滑鼠右鍵,再按一下 [內容]In the console tree, under the Namespaces node, right-click a domain-based namespace, and then click Properties .

  3. [進階] 索引標籤上,選取您要最佳化命名空間的一致性或延展性。On the Advanced tab, select whether you want the namespace optimized for consistency or scalability.

    • 如果裝載命名空間的伺服器有 16 個或更少,請選擇 [最佳化一致性]Choose Optimize for consistency if there are 16 or fewer namespace servers hosting the namespace.
    • 如果有超過 16 個命名空間伺服器,則選擇 [最佳化延展性]Choose Optimize for scalability if there are more than 16 namespace servers. 這樣雖然會減少網域主控站 (PDC) 模擬器的負載,不過卻會增加將命名空間的變更複寫到所有命名空間伺服器的時間。This reduces the load on the Primary Domain Controller (PDC) Emulator, but increases the time required for changes to the namespace to replicate to all namespace servers. 將變更複寫到所有伺服器之前,使用者可能會看到不一致的命名空間。Until changes replicate to all servers, users might have an inconsistent view of the namespace.

注意

若要使用 Windows PowerShell 來設定命名空間輪詢模式,請使用 Set-DfsnRoot EnableRootScalability Cmdlet,此功能已在 Windows Server 2012 中推出。To set the namespace polling mode by using Windows PowerShell, use the Set-DfsnRoot EnableRootScalability cmdlet, which was introduced in Windows Server 2012.
