Novell Backbone in MS World

My team is attempting to incorporate A Novell 5.1 backbone into our Win 2k server array. I am not even sure where to begin. I am assuming that the ADS and NDS will not work coheseively together, and i want to join the MS servers into the Novell tree. However, i am also running exchange 2000 on one box and i read that it needed to be run on a Domain Controller.
