import static address details into Win 2K3 DHCP

I am corrently migrating my NT4 network onto W2K3 with AD and in order to privide greater connectivity security on one of our subnets I need DHCP to allocate IP addresss only to devices where we know the MAC address. This I can configure and have tested on a small scale however now that I want to deploy it to all of the PCs on that subnet I need a way to import in bulk the IP and MAC addresses of the machines from the asset database that we maintain into the Microsoft DHCP configuration. The asset database is held in a SQL table but can be exported into any format that is necessary. Are there any tools to do this or can I do it using scripting? All suggestions welcome
