SV-88295r1_rule Domain controllers must be configured to allow reset of machine account passwords.

Vulnerability discussion

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.

Check content

This applies to domain controllers. It is NA for other systems. 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: RefusePasswordChange Value Type: REG_DWORD Value: 0x00000000 (0)

Fix text

Configure the policy value for Computer Configuration >> Windows Settings >> Security Settings >> Local Policies >> Security Options >> "Domain controller: Refuse machine account password changes" to "Disabled".

Pro Tips

Lavender hyperlinks in small type off to the right (of CSS class id, if you view the page source) point to globally unique URIs for each document and item. Copy the link location and paste anywhere you need to talk unambiguously about these things.

You can obtain data about documents and items in other formats. Simply provide an HTTP header Accept: text/turtle or Accept: application/rdf+xml.
