Description
The longer a password is in use, the greater the opportunity for someone to gain unauthorized knowledge of the password. The password for the built-in Administrator account must be changed at least annually or when any member of the administrative team leaves the organization. It is highly recommended to use Microsoft's Local Administrator Password Solution (LAPS). Domain-joined systems can configure this to occur more frequently. LAPS will change the password every "30" days by default. The AO still has the overall authority to use another equivalent capability to accomplish the check.

Review the password last set date for the built-in Administrator account. Domain controllers: Open "Windows PowerShell". Enter "Get-ADUser -Filter * -Properties SID, PasswordLastSet \| Where SID -Like "*-500" \| FL Name, SID, PasswordLastSet".

Enter 'Net User [account name] \| Find /i "Password Last Set"', where [account name] is the name of the built-in administrator account. (The name of the built-in Administrator account must be changed to something other than "Administrator" per STIG requirements.) If the "PasswordLastSet" date is greater than one year old, this is a finding.
