找了好久，终于找到了链接，链接见下：
https://support.microsoft.com/en-us/help/4034661/windows-10-update-kb4034661
此KB修复的问题中有一条，如下：
Addressed issue where a computer account loses its domain membership with the error 1789, “The trust relationship between this workstation and the primary domain failed.” The same problem happens internally when a user password cannot be changed with error 0xc0000206, “The size of the buffer is invalid for the specified operation.”

下载后，在win server 2016 DC上安装
完成后问题解决。
