ฉันมีโน้ตบุ๊กที่ใช้ Windows 7 เข้าร่วมกับ Win2008 Domain
เมื่อโน้ตบุ๊กเชื่อมต่อกับเครือข่ายโดเมนมันจะบู๊ตในเวลาน้อยกว่า 60 วินาที แต่เมื่อมันถูกตัดการเชื่อมต่อจากเครือข่าย (ปิดใช้งาน NICs) อาจใช้เวลา 5-10 นาทีในการเข้าสู่ระบบแจ้ง การเข้าสู่ระบบใช้เวลาเพียงไม่กี่วินาทีไม่ว่าจะเปิดหรือปิดเครือข่ายโดเมน แต่เวลาการบูตจะได้รับผลกระทบอย่างมาก
ในการวินิจฉัยปัญหานี้ฉันเรียกใช้การตรวจสอบกระบวนการและมีการบันทึกเวลาบูต ผู้ร้ายดูเหมือนจะเป็นการดำเนินการ "FileSystemControl" ในกระบวนการ svchost
คุณจะเห็นว่าการทดสอบนั้นใช้เวลา 5 นาทีในกระบวนการ
นี่คือข้อมูลเพิ่มเติมจาก procmon บนอินสแตนซ์เฉพาะของ svchost:
