一、NTP时钟端口打开

　　检查电脑防火墙，确保打开端口“123”（NTP服务端口）。可手动添加入/出站规则。

　　（一般不需要设置）

二、打开NTP时钟服务器功能

　　1、  运行”gpedit.msc”，按下图设置NTP服务器。

 

 

 

注：配置/启用Windows NTP客户端设置成“未配置”。启用Windows NTP服务器设置成“启用”。

 

另：打不开gpedit.msc的WINDOWS，可设置注册表：HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\W32Time\TimeProviders\NtpServer

　　Enabled 设定为 1（默认0）

三、启动WINDOW时间服务

1、  运行”services.msc”，按下图设置time服务。

 

 

 

四、用电脑测试NTP服务器

　　以上设置电脑后使得电脑变成了一台“NTP服务器”，用另外一台电脑去同步它就能获取到此“NTP服务器”的时间了。如下图：

 

 

 

 

注：往往或肯定不能同步成功，原因是： 

　　需要更改注册表选项：HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\W32Time\Config\AnnounceFlags 设定为 5 （默认 10）
