Windows 2003 Server – Firewall blocks DHCP Server

I was insttaled Windows 2003 Server as Domain Controller wigh Active Directory, DNS Server and DHCP Server. With Windows XP Professional insttaled at my notebook, I can’t get IP address from DHCP Server when Windows Firewall was activated. When I disable Windows Firewall, I get IP address succesfully. There are some configuration at Windows Firewall that permit client to get IP address?

Thanks,
