# Windows系统配置NTP服务器

## 1.开启Windows 时间服务。

* 在桌面上右击“计算机”，选择“管理”，然后选择“服务”。或者按下windows键+R 组合键打开运行，输入： services.msc
* 选中“Windows Time”，设置为开启，这样就可以将“Windows Time”这一个服务打开。

## 2.修改注册表

* “开始”--》“运行”--》输入“regedit”打开注册表，在注册表中依次展开：HKEY\_LOCAL\_MACHINE、SYSTEM、CurrentControlSet、Services、W32Time、TimeProviders、NtpServer， 在NtpServer项的右侧键值Enablied，将默认的0改为1，1为启用NTP服务器。

* 再在注册表中依次展开：HKEY\_LOCAL\_MACHINE、SYSTEM、CurrentControlSet、Services、W32Time、Config 找到Config项右侧的AnnounceFlags。把默认的10改为5，5的意思就是自身为可靠的时间源。
