Analyze the system using the Security Configuration and Analysis snap-in.
Expand the Security Configuration and Analysis tree view.
Navigate to Account Policies >> Account Lockout Policy.

Configuring this to "0", requiring an administrator to unlock the account, is more restrictive and is not a finding.
