Assessment Title

Rule Text

Windows Server 2022 domain controllers must be configured to allow reset of machine account passwords.

Description

Discussion Text

Enabling this setting on all domain controllers in a domain prevents domain members from changing their computer account passwords. If these passwords are weak or compromised, the inability to change them may leave these computers vulnerable.

How this relates to the STIG checklist: STIG vs SCAP benchmark.
