Are you trying to use windows server on an HFS formatted disk, or just simply access the contents of an HFS formatted disk from a NTFS/FAT formatted disk with win2k3 installed?

If that ladder and you don't have a mac running the HFS disk so you can access it via a network, the options Krusher117 gave you should work nicely.  If you are talking about the first option, I have no clue, I am not even sure thats possible.
