Specifies whether the user sees the menu option "Use Local Names", and can disable corporate resolution of flat host names and instead use local name resolution. If enabled, the user can right-click the DCA icon and then click Prefer Local Names. If this setting is disabled, the menu option does not appear on the DCA menu.
If the user selects Prefer Local Names, DirectAccess stops sending name resolution requests to the internal corporate DNS servers. Instead, the client uses whatever local name resolution is available to the client computer in its current network configuration.
