Domain member: Maximum machine account password age

Verified with Windows Security Options 25H2 — updated on July 13, 2026

Security policy

This is a Security Options policy (Windows Settings > Security Settings), applied by the security engine — not an Administrative Template (ADMX). In GPMC/gpedit it is configured under Local Policies > Security Options.

Path in the GPO console

Computer Configuration\Windows Settings\Security Settings\Local Policies\Security Options\Domain member

Description

This setting specifies the maximum number of days a domain member keeps its machine-account password before changing it. The default is 30 days. A longer interval increases the lifetime of a compromised trust secret, while an excessively short interval can complicate replication and recovery.

Registry

HKLM System\CurrentControlSet\Services\Netlogon\Parameters

Value name: MaximumPasswordAge

More options available

Options

Domain member: Maximum machine account password age (days)
MaximumPasswordAge decimal - range 0-4294967295

Export Builder

BETA

Configure the state, scope and options, then generate .reg, PowerShell, Intune and SCCM outputs — or add the setting to a multi-setting collection.

These exports write the registry — this is not a managed GPO.

Security policy setting: a domain GPO (Security Settings) can overwrite this registry value at the next policy refresh. Prefer configuring it via GPMC > Security Options.
