因此，我正在尝试在这台 Windows 10 家庭计算机上安装 NTP 服务器。我尝试了各种教程来启用 w32time 的服务器模式，然后当失败时我最终安装了Meinberg NTP，但无济于事。所以事情是这样的：服务声称它们工作正常，但 NTP 端口 (123) 仍然关闭。我已经关闭了防火墙。我没有安装我所知道的其他安全软件。这是一个日志：（请注意，由于我重新启动了计算机，因此该服务在日志文件的中间停止并启动。）

该服务声称在许多地址上侦听端口 123，并 netstat -abn同意 ntpd.exe 在许多地址上侦听 123，但 nmap 相反地表示在我尝试的每个本地指向地址上都关闭了 123。谁能解释为什么？
