배경:
내 LAN의 Windows Server 2012 R2 도메인 컨트롤러는 몇 년 동안 외부 시간 서버 없이 실행되어 왔으며 이제 마침내 동기화되었습니다. 원래 예상 시간보다 약 2분 정도 느리게 실행되었습니다. DC의 명령줄은 다음과 같습니다.

o:+106이 컴퓨터가 time.windows.com반환된 것보다 106초 늦었다는 것을 나타내는 값을 관찰하십시오 .
나는 그것을 다음과 같이 재구성했습니다.
w32tm /config /manualpeerlist:"time.windows.com,0x1" /syncfromflags:manual /reliable:yes /update
이제 w32tm /stripchart정확한 시간이 표시됩니다.

문제:
LAN에 있는 내 개인 컴퓨터, 도메인 구성원 워크스테이션이 DC에 동기화되어 잘못된 시계를 상속했습니다.
실행했지만 w32tm /update여전히 ~102초의 "루트 분산"이 있는 로컬 컴퓨터의 시계가 업데이트되지 않았습니다.
w32tm시계를 왜곡하는 데 시간이 걸린다는 것을 알고 있으므로 w32tm /stripchart /computer:mydomaincontroller.example.com무슨 일이 일어나는지 확인하기 위해 계속 열어 두었습니다(아래 콘솔 출력 내부에서 스크롤하여 13:48:12).

그래서 내 데스크톱 컴퓨터는 내 도메인 컨트롤러의 시계와 일치하도록 시계를 왜곡하기로 결정했지만... 계속해서 왜곡되도록 허용하고 지난 7분 동안 o:-58.14s.
내 질문:
- 시계 왜곡이나 느린 업데이트 없이 즉각적인 시간 동기화를 강제하려면 어떻게 해야 합니까? 단, 부모 시간 원본 컴퓨터와 일치하도록 컴퓨터 시계를 엄격하고 빠르게 재설정해야 합니까?
- 내 컴퓨터의 시간이 동기화되기 시작한 다음 초과되는 이유는 무엇입니까?
업데이트:
나는 /stripchart창문을 열어두었고 결국 이런 일이 일어나는 것을 보았습니다.
