Check content

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: \Software\Policies\Microsoft\Windows\TCPIP\v6Transition\IPHTTPS\IPHTTPSInterface\ Value Name: IPHTTPS_ClientState Type: REG_DWORD Value: 3

Fix text

Configure the policy value for Computer Configuration -> Administrative Templates -> Network -> TCPIP Settings -> IPv6 Transition Technologies -> "Set IP-HTTPS State" to "Enabled: Disabled State". Note: "IPHTTPS URL:" must be entered in the policy even if set to Disabled State. Enter "about:blank".

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.
