Simple Golden Triangle (OD/AD) How To?

Hello, I know that there are a Bazzilion posts out there all asking about setting up a golden triangle (I think I have read them all!) The problem I am having is that they all seem inconsistant, and none of them have successfully guided me to a working setup (I realize that the single point of failure in this scenario is me) So could anyone point me to a definitive guide for setting up a golden triangle? Here are my vitals: OS X Server running 10.4.11 (This would be the OD Master... I think) Windows Server 2003 Domain (3 servers, One File server hosting User accounts, One server hosting Exchange, One hosting DHCP,DNS, and other Misc apps) I run a small/medium sized windows network with about 90 users, We have about 10 Macs doing Video/Graphics applications. I would like to get the Macs integrated into the AD so that the mac users can log onto either a windows machine or a mac and have access to their files. I would like the mac home directories to be stores on the windows file server so that they are part of the normal backup routine. I would also like to be able to give certain Windows users login access to the Mac machines and limit thier application access. What I really need is a good step by step from a brand new 10.4 installation. I have rebuilt the OS X server 4 times now, and I am willing to do it again. Any direction or assistance would be appreciated. Thanks!
