Why W2K8 DC can't works as DHCP server?

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?

Did you shut down the DHCP from the router before you authorized the DHCP server on the DC? YOur DC should be also the DHCP server in this scenario. You also may not have authorized the DHCP server. This is a common mistake.

Are you activating and authorising the scope on Windows 2008?
Also if the DHCP is still active on the firewall then the Windows 2008 will shut it's DHCP down.

This is the sequences I did:

- On server, create scope, configuring all needed settings
- Off the DHCP
- Logon to the firewall, off the DHCP
- On server, on the DHCP, make sure it is authorize

Initially, few wireless workstations work, but suddenly, all failes.

Is it has to delete the arp? " arp -d"?

How about the computer browser service in w2k8 server? My previous enconter is, this service has some known bug, and has to be closed down.

Are you getting error messages in the error logs?

Do I have to explicitly open in the firewall?
