Win2008 도메인에 가입된 Windows 7을 실행하는 노트북이 있습니다.
노트북이 도메인 네트워크에 연결되면 60초 이내에 부팅됩니다. 그러나 네트워크 연결이 끊어지면(NIC 비활성화) 로그인 프롬프트에 도달하는 데 5~10분이 걸릴 수 있습니다. 도메인 네트워크에 있든 없든 로그인하는 데는 몇 초 밖에 걸리지 않지만 부팅 시간은 상당한 영향을 받습니다.
이 문제를 진단하기 위해 프로세스 모니터를 실행하고 부팅 시 로깅을 수행했습니다. 범인은 svchost 프로세스에서 발생하는 "FileSystemControl" 작업인 것 같습니다.
테스트 결과 해당 프로세스에 5분 이상 소요된 것을 볼 수 있습니다.
다음은 svchost의 특정 인스턴스에 대한 procmon의 추가 정보입니다.

이 문제를 더 자세히 조사하고 해결하려면 어떻게 해야 합니까? "FileSystemControl"은 부팅 시간이 길어지는 원인에 대해 많은 정보를 제공하지 않습니다.
답변1
다른 사람이 만든 GPO에 묻혀 있던 두 가지 설정이 밝혀졌습니다.
"시작 정책 처리 대기 시간 지정" 값이 5분으로 설정되어 있고 "컴퓨터 시작 시 항상 네트워크 대기"가 활성화되어 부팅 시간이 길어졌습니다.
