Title

The computer account password must not be prevented from being reset.

Control

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: DisablePasswordChange Value Type: REG_DWORD Value: 0

Discussion

Computer account passwords are changed automatically on a regular basis. Disabling automatic password changes can make the system more vulnerable to malicious access. Frequent password changes can be a significant safeguard for the system. A new password for the computer account will be generated every 30 days.
