Check content

If the following registry value doesn’t exist or is not configured as specified, this is a finding: Registry Hive: HKEY_LOCAL_MACHINE Subkey: \Software\Policies\Microsoft\Windows NT\Terminal Services\ Value Name: fSingleSessionPerUser Type: REG_DWORD Value: 1 Documentable Explanation: If the system has the role as a Terminal/Remote Desktop Server or the site is using remote desktop services for remote administration, this requirement needs to be documented with the IAO.

Fix text

Configure the policy value for Computer Configuration -> Administrative Templates -> Windows Components -> Remote Desktop Services -> Remote Desktop Session Host -> Connections “Restrict Remote Desktop Services users to a Single Remote Desktop Services Session” to “Enabled”.

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.
