Verify the effective setting in Local Group Policy Editor.Run "gpedit.msc".Navigate to Local Computer Policy >> Computer Configuration >> Windows Settings >> Security Settings >> Account Policies >> Account Lockout Policy.If the "Account lockout duration" is less than "15" minutes (excluding "0"), this is a finding.For server core installations, run the following command:Secedit /Export /Areas SecurityPolicy /CFG C:\Path\FileName.TxtIf "LockoutDuration" is less than "15" (excluding "0") in the file, this is a finding.Configuring this to "0", requiring an administrator to unlock the account, is more restrictive and is not a finding.
