Automounting sharepoints from a Windows server?

I’ve got a mixed network, with an OD Master running on 10.4.2 and numerous Replicas. I’ve also got a few boxes running Server 2003.

I’d like to be able to host user home directories on the Server 2003 machines, and have them automount for Mac and PC clients. The shares are setup on my 2003 servers, I can mount them, I have read and write access to them, but I can’t figure out how to set them up as valid sharepoints on the OD Master.

Is there a way to set this up in WGM? Is this even possible? Thanks in advance.
