RRAS and DHCP Server (same server) problem

Hello,

I have a small company with 10 workstations and 1 server hp 350 g5. It’s a Server 2003 with DC role, DHCP, DNS, RRAS Server. I have 2 NIC’s because of the RRAS. RRAS is fully configurated, also all the roles. The problem is that DHCP isn’t working (no leases for lan). Workstations receive automatic private address. Any ideas ??? urgent please.

Thanks
