Routing and DHCP

I’ve setup a w2K network with two subnets. The problem is that the DHCP clients on the subnets cannot receive an IP address from the DHCP server.The three scopes are active. Scope options are set to define routers, and DNS. Routing is installed on the server responsible, along with RIP2 and BOOTP. The network is dual boot. Everythig works with NT. Any ideas.
