Internet Connection wizard error on Small Business Server 2003

Hello all,

I need help setting up my internet of the SBS 2003. This is my first time installing one. I have two nic cards, one for LAN and the other for internet. I have an ATT DSL modem and have assigned LAN nic ip address 192.168.1.200
Subnet : 255.255.255.0
Default gateway 192.168.1.254
DNS: 192.168.1.200

and for internet connection nic assigned ip address 192.168.1.66
Subnet : 255.255.255.0
DNS: 192.168.1.200

I selected direct broadband for internet connection but after click next a few times its giving an error on the network component of the configuration

How do I get around this?
