An error occurred while Windows was synchronizing with *.*.*.*

问题描述：An error occurred while Windows was synchronizing with time.windows.com

                或者An error occurred while Windows was synchronizing with 10.80.2.80（内部时间服务器）

解决方法：

1. Most of the time you get the error is due to the time server being down, so try again later.
   

    大多时候出现这种错误是因为时间服务器服务关闭，所以等一会再试。（内部时间服务器可自己重启）

2. Try another Server. ( time.nist.gov )

   尝试其他时间服务器。（time.nist.gov）

3. Your firewall might be blocking W32Time, disable firewall, update time and enable again.

   关闭防火墙，再同步时间。

4. The following steps will stop and start the time update application.

   按照以下步骤停止和启动时间更新程序。

   Start > Run cmd.exe
   net stop w32time
   w32tm.exe /unregister
   w32tm.exe /register
   net start w32time
