DNS not active in my Mac Book Air, but is active in my MacBook Pro and Mac Mini. All connected to the same router. Major difference is when I do a Status check, the IP address shows up in both the MacMini and the MB Pro's window, but does not show in the MB Air. When I log into DNS site, it appears that all the parameters between the 3 computers are the same. How do I get the IP address to display in the Air's status window?
