Domain member: Disable machine account password changes

Applies to

  • Windows 11
  • Windows 10

Describes the best practices, location, values, and security considerations for the Domain member: Disable machine account password changes security policy setting.


The Domain member: Disable machine account password changes policy setting determines whether a domain member periodically changes its machine account password. Setting its value to Enabled prevents the domain member from changing the machine account password. Setting it to Disabled allows the domain member to change the machine account password as specified by the value of the Domain member: Maximum machine account password age policy setting, which is every 30 days by default.

By default, devices that belong to a domain are automatically required to change the passwords for their accounts every 30 days. Devices that are no longer able to automatically change their machine password are at risk of a malicious user determining the password for the system's domain account. Verify that the Domain member: Disable machine account password changes option is set to Disabled.

Possible values

  • Enabled
  • Disabled

Best practices

  1. Don't enable this policy setting. Machine account passwords are used to establish secure channel communications between members and domain controllers and between the domain controllers within the domain. After it's established, the secure channel transmits sensitive information that is necessary for making authentication and authorization decisions.

  2. Don't use this policy setting to try to support dual-boot scenarios that use the same machine account. If you want to configure dual-boot installations that are joined to the same domain, give the two installations different computer names. This policy setting was added to the Windows operating system to help organizations that stockpile pre-built computers that are put into production months later. Those devices don't have to be rejoined to the domain.

  3. You may want to consider using this policy setting in specific environments, such as the following ones:

    • Non-persistent Virtual Desktop Infrastructure implementations. In such implementations, each session starts from a read-only base image.
    • Embedded devices that don't have write access to the OS volume.

    In either case, a password change that was made during normal operations would be lost as soon as the session ends. We strongly recommend that you plan password changes for maintenance windows. Add the password changes to the updates and modifications that Windows performs during maintenance windows. To trigger a password update on a specific OS volume, run the following command:

    Nltest /sc_change_pwd:<AD DS domain name>

    In this command, <AD DS domain name> represents the domain of the local computer. For more information about maintenance windows and non-persistent VDI implementations, see Optimizing Windows 10, version 1803, for a Virtual Desktop Infrastructure (VDI) role: VDI optimization principles: Non-Persistent VDI.

Policy management

This section describes features and tools that are available to help you manage this policy.

Restart requirement

None. Changes to this policy become effective without a device restart when they're saved locally or distributed through Group Policy.

Security considerations

This section describes how an attacker might exploit a feature or its configuration, how to implement the countermeasure, and the possible negative consequences of countermeasure implementation.


By default, devices running Windows Server that belong to a domain automatically change their passwords for their accounts every certain number of days, typically 30. If you disable this policy setting, devices that run Windows Server retain the same passwords as their machine accounts. Devices that can't automatically change their account password are at risk from an attacker who could determine the password for the machine's domain account.


Verify that the Domain member: Disable machine account password changes setting is configured to Disabled.

Potential impact

None. This non-impact state is the default configuration.
