About this update. Network reporting tools, such as Netstat and PowerShell-based Get-NetTcpConnection don't report Transport Control Protocol (TCP) or User Datagram Protocol (UDP) port usage correctly since Windows Vista because some new TCP/IP features are introduced.

This issue occurs because an error in the Nettcpip.inf file causes the settings in the DHCP Client service to revert to the default settings. Resolution Hotfix information. A supported hotfix is available from Microsoft. However, this hotfix is intended to correct only the problem that is described in this article.

Auto-reuse port range You can set the auto-reuse port range by using Windows PowerShell cmdlets. This separate port range is defined by the following two new TCP template parameters:

Note Restart requirement: You have to restart the computer after you change the AutoReusePortRange settings for the setting to take effect.. After the reboot you can verify your defined settings using the PowerShell command: Get-NetTCPSetting. Hotfix information. A supported hotfix is available from Microsoft Support.

In the All or part of the file name box, type nettcpip.inf, and then click Search. In the results pane, right-click Nettcpip.inf , and then click Install . Restart the computer.

自动重复使用端口范围 您可以使用 Windows PowerShell cmdlet 设置自动重复使用端口范围。 由以下两个新 TCP 模板参数定义此单独的端口范围： AutoReusePortRangeStartPort. AutoReusePortRangeNumberOfPorts. 您可以通过使用 PowerShell cmdlet集 NetTCPSetting设置这些参数。 从端口 1024 独占到端口包括 65535 是智能端口范围的下限。 智能端口范围可部分覆盖的动态端口范围。 在这种情况下，这两个区域中的端口将仅用于智能端口分配。 应用程序要使用这些新的套接字参数，如以下示例所示，必须定义自动重复使用端口范围：

由于引入了一些新的 TCP/IP 功能，因此基于 Netstat 和基于 PowerShell 的 NetTcpConnection 的网络报告工具不会在 Windows Vista 中正确报告传输控制协议（TCP）或用户数据报协议（UDP）端口使用情况。 此更新会将一些更改引入到 Netstat 和 NetTcpConnection，以便它们能够正确报告 Windows Server 2012 R2 中的 TCP 或 UDP 端口用法。 如何获取此更新程序. 重要说明 如果你在安装此更新后安装了语言包，则必须重新安装此更新。 因此，我们建议你先安装所需的全部语言包，然后再安装此更新程序。 有关更多信息，请参阅 添加语言包至 Windows 。 方法 1： Windows 更新.
