Configuring this security setting

You can configure this security setting by opening the appropriate policy and expanding the console tree as such: Computer Configuration\Windows Settings\Security Settings\Local Policies\Security Options\

For specific instructions about how to configure security policy settings, see Edit security settings on a Group Policy object.


  • This security setting should not be enabled. Computer account passwords are used to establish secure channel communications between members and domain controllers and, within the domain, between the domain controllers themselves. Once it is established, the secure channel is used to transmit sensitive information that is necessary for making authentication and authorization decisions.

  • This setting should not be used in an attempt to support dual-boot scenarios that use the same computer account. If you want to dual-boot two installations that are joined to the same domain, give the two installations different computer names.
