I too have the same problem. SP1 does come with directx 9.0c, but it is incomplete. I have seen freeware tools to remove the current version of directx so i can install a recent 9.0c redist package, but all complain about the version, maybe because of sp1 being installed (but i love the firewall!) If anyway has a way to install a redist of 9.0c on win2k3 sp1 let me know ! Ive been stumped on this for months...
