Windows Server 2022 maximum age for machine account passwords must be configured to 30 days or less.

Computer account passwords are changed automatically on a regular basis. This setting controls the maximum password age that a machine account may have. This must be set to no more than 30 days, ensuring the machine changes its password monthly.

This is the default configuration for this setting (30 days).

If the following registry value does not exist or is not configured as specified, this is a finding:

Registry Hive: HKEY_LOCAL_MACHINE Registry Path: \SYSTEM\CurrentControlSet\Services\Netlogon\Parameters\

Value Name: MaximumPasswordAge

Value Type: REG_DWORD Value: 0x0000001e (30) (or less, but not 0)

This is the default configuration for this setting (30 days).

Configure the policy value for Computer Configuration >> Windows Settings >> Security Settings >> Local Policies >> Security Options >> Domain member: Maximum machine account password age to "30" or less (excluding "0", which is unacceptable).
