WPA2 GPO issue

I need help with WPA2 GPO. We have windows server 2003 SP2 DC with IAS. I can deploy GPO with WPA but I need to get WPA2. Per MS I am creating GPO from the vista PC and have extended the wireless schema for the AD. But client is not able to see the GPO. I have used following two article from MS website for the configuration.
