Parent not seeing child PDC

I set up a new 2003 Standard server and made it the PDC of a child domain. On the parent PDC I can see the child domain but not the child PDC when I try to manage it. I've checked Trust and everything is in order, and I've checked the Operations Master roles. Since I'm not running a mixed mode domain I went ahead and raised the Domain Functional Level on both servers to 2003 native.

Am I missing something?
