如果您在“本地连接”属性中显示的此连接使用下列项目列表中单击Internet协议(TCP/IP)项，您将发现卸载按钮不可用（被禁用）。这是因为传输控制协议/Internet协议(TCP/IP)堆栈是MicrosoftWindowsServer2003的核心组件，不能删除。
在有些情况下，可能需要重新安装TCP/IP以使TCP/IP堆栈恢复为原始状态。可以使用NetShell实用程序重置TCP/IP堆栈，使其恢复到初次安装操作系统时的状态。
NetShell实用程序(netsh)是一个命令行脚本编写工具，您可以使用此实用程序配置并监视WindowsServer2003联网。此工具提供了交互式网络外壳程序接口。
您可以使用该实用程序的Internet协议(IP)上下文中的reset命令重写以下与TCP/IP相关的注册表项：
SYSTEM\CurrentControlSet\Services\Tcpip\Parameters\
SYSTEM\CurrentControlSet\Services\DHCP\Parameters\
运行此命令的结果与删除并重新安装TCP/IP协议的效果相同。
命令语法
netshintipreset
要使用netsh命令重置TCP/IP堆栈，您必须指定记录命令结果的日志文件的名称。如果输入了本文“命令示例”一节中介绍的任一命令，当前计算机中的TCP/IP堆栈将被重置，且该xx作的活动将被记录到命令行中指定的Resetlog.txt文件。在第一个示例中，日志文件被创建在当前文件夹中；在第二个示例中，则指定了Resetlog.txt日志文件的完整路径。
备注：如果该文件的名称与目标文件夹中的现有日志文件的名称相同，则会将新日志文件的信息附加到现有文件的结尾处。
命令示例
下面的示例说明了如何使用netsh命令重置TCP/IP协议堆栈。
示例1
单击开始，然后单击运行。
在打开框中键入cmd，然后单击确定。
在命令提示符后键入以下命令，然后按ENTER键：
netshintipresetresetlog.txt
备注：在上面的命令中，“int”是interface命令的缩写形式。
键入exit，然后按ENTER键。
示例2
单击开始，然后单击运行。
在打开框中键入cmd，然后单击确定。
在命令提示符后键入以下命令，然后按ENTER键：
netshintipresetc:\resetlog.txt
键入exit，然后按ENTER键。
要查看有关命令的帮助，请键入空格，然后键入?。即会显示有关netsh命令子上下文中可用命令的其他帮助。例如，要查看上一节中介绍的netsh命令，应在命令提示符后键入以下命令：
键入netsh?，然后按ENTER键。
键入netshint?，然后按ENTER键。
键入netshintip?，然后按ENTER键。
键入netshintipreset?，然后按ENTER键。
NETSHINTIPRESET的日志文件示例
以下是一个日志文件的示例，该日志文件是由运行ipreset命令后的netsh生成的。根据发出命令的计算机上不同的配置，实际的日志文件也会有所不同。通常，如果没有替换TCP/IP注册表项的原始配置，则不会在文件中记录任何操作。
