Windows Home Folders

I’m setting up an Open Directory domain for several Macs and several PCs. The Macs are good to go. The PCs (running Vista) are able to log in using OD user accounts, but a home folder is created on the local drive in C:\Users and remains in the local folder.

I need Windows home folders to behave like Portable Home Folders on the Mac side. I would actually prefer NOT to use the same home folder for a user in both Mac and Windows–but a given user’s Mac home folder and his Windows home folder should both sync back to the server. The main concern is that these machines will be frequently re-imaged, and so locally-stored user home folders will be destroyed when this happens, so I need to make sure all home folders are rock-solid reliably stored on the server so that when a machine is reimaged and re-joined to the domain a user can log in to his or her user account and have their home folder be synced from the server and have everything in place just as it was before the re-imaging.
