Cannot get Windows 7 laptop to connect to non-broadcasted wireless network

At work We are running a RADIUS server on a windows 2003 current service release and patches. I am trying to use a laptop running windows 7 to connect to a nonbroadcasted wireless network that we have running for our internal users. I can take the laptop downgrade it to vista or XP and the wireless works. As soon as I install windows prof 7 and join the computer to our AD domain ... I am unable to connect to the nonbroadcasted network. I have the most up to date network cars drivers installed on the HP laptop. All the settings are greyed out under the wireless properties section. Any suggestions?
