如何在 Windows XP 中重置 Internet 协议 (TCP/IP)

在Windows XP(简称Windows XP)的连接属性对话框中，如果点击“Internet协议(TCP/IP)选项，“卸载”按钮为灰色，是不可用的。这是因为TCP/IP协议是Windows Server XP的核心组件，不能删除。

　　如果我们需要将TCP/IP重置到原始状态，该怎么办呢？此时，我们可以借助“netsh”命令行工具来解决这一问题。在“运行”对话框中输入“cmd”，打开“命令提示符”窗口，然后输入命令行“netsh int ip reset resetlog.txt”或“netsh int ip reset c:\resetlog.txt”并按回车键。其中的“reset”命令可以重写与TCP/IP相关的注册表项“System\CurrentCon trolSet\Services\Tcpip\Parameters\”和“System\CurrentControlSet\Services\DHCP\Parame ters\”，运行以上命令的结果与删除并重新安装TCP/IP的效果相同。

　　此外，两个命令行的不同之处仅仅在于“resetlog.txt”日志文件的存储位置有所区别。前者是将日志文件创建在当前文件夹中，而后者则指定了具体的保存路径。

步骤：

1. 开始，运行。
2. 输入CMD，回车。
3. 输入“netsh int ip reset resetlog.txt”或“netsh int ip reset c:\resetlog.txt”，回车。

概要 当查看网络接口的组件列表时，您可能会注意到当选择 Internet 协议 (TCP/IP) 时将禁用卸载按钮。在 Windows XP 中，TCP/IP 栈被视为操作系统的核心组件；因此 Windows XP 中不能卸载 TCP/IP。

在某些极端情况下，重新安装 Internet 协议栈可能是最合适的解决方案。使用 NetShell 实用程序，您可以将 TCP/IP 栈重置为初始状态，即与安装操作系统时相同的状态。

更多信息
NetShell 实用程序 (netsh) 是一个命令行脚本接口，用于配置和监控 Windows XP 网络。此工具为用户提供了交互式的网络 Shell 接口。

在 Windows XP 中，reset 命令在 NetShell 实用程序的 IP 上下文中可用。当执行此命令时，它重写 Internet 协议 (TCP/IP) 栈使用的相关注册表项，实现与删除并重新安装协议相同的结果。

SYSTEM\CurrentControlSet\Services\Tcpip\Parameters\ SYSTEM\CurrentControlSet\Services\DHCP\Parameters\ 命令使用 netsh int ip reset [log_file_name]

若要成功执行此命令，您必须指定一个日志文件名称，netsh 执行的操作将被记录在该日志文件中。例如，在命令提示符处键入本文稍后“命令示例”一节中列出的任何一个示例都将重置系统上的 TCP/IP 栈并将执行的操作记录在日志文件 Resetlog.txt 中。第一个示例在当前目录中创建日志文件，而第二个示例演示在指定的路径中创建日志。不管是哪种情况，如果指定的日志文件已存在，则新日志将附加在现有文件的末尾。 命令示例 netsh int ip reset resetlog.txt
netsh int ip reset c:\resetlog.txt NETSH INT IP RESET 的示例日志文件以下是发出 IP 重置命令后 netsh 生成的日志文件的示例。根据发出命令的系统上不同的配置，实际的日志文件也会有所不同。在某些情况下，该文件中可能未记录任何操作。通常如果未从原始配置更改 TCP/IP 注册表项，则会出现这种情况。
