This is working with W2K8 AD domain, with one w2k8 sp2 DC. Besides this, there are Netscreen ST5 firewall and WG54 AP. Quite a number of wireless client workstations. In the past, firewall works as DHCP server for both LAN and wireless clients. I'm thinking of moving the role of DHCP to DC, but failed. This is because client can't get IP from DC. Any thing I miss out?
