Enabling Wireless Before Logon for Active Directory

We are purchasing computers in the next week on our Enterprise network and will have a mix of Macs and PCs. We are currently running our AD server on Windows Server 2008R2. We use folder redirection and mounting for all of our users, and would want the folder to automount on login for Apple. We have a LAN and also a radius authenticated wireless network on PEAP. I have successfully joined the AD with my MB Pro, but cannot login to AD due to the wireless not working before login. Has anyone ran across this issue before or know of a fix?
