"The ghost in the machine," Leo said.

The screen scrolled to life. It was a confession sheet for every workstation on the domain. He saw the culprit immediately: a rogue "AppLocker" policy from a test Organizational Unit had been accidentally linked to the root of the domain. The policy’s GUID— {4D3F9A2B-1C8E-4F7A-9B2C-3D5E6F7A8B9C} —glowed like a digital fingerprint. group policy command prompt

Leo minimized the Command Prompt. He looked at the blank black screen, then back at Carl. "The ghost in the machine," Leo said

His fingers flew.

He launched psexec —a Sysinternals tool that let him whisper commands directly into a remote PC’s ear. He targeted the CFO’s machine first. His command was ruthless: He saw the culprit immediately: a rogue "AppLocker"
