By design, the built-in Administrator account is exempt from the Account Lockout Policy. This ensures that critical administrative access is always available, even in cases of brute force or accidental lockout attempts. The logic: If this account were locked and no other Domain Admin account exists, it could prevent recovery during emergencies.
