Hi all, We used Cisco Wireless LAN controller and use Windows RADIUS to authenticate. In controller, if we configure it to use Windows 2003 DHCP server and users with wireless connections can get the IP addresss from DHCP. If we configure controller to use Windows 2008 R2 DHCP server and users are not able to get IP address from Windows 2008 R2 DHCP server. Can anyone help?

I know for sure that this is working. So I would rather check the windows firewall or any other firewall, IP roting between WLC and the DHCP server. And also check that you have configured the scopes in DHCP with the same IP subnet. Regards, Lutz
