Moving My Documents Folder

On systems running Windows 2000 and XP Professional the ?My Documents? folder defaults to the C drive. Most if not all the new PCs come with a small C and a large D partition. I have PCs where up to 15 people share the same PC (roaming profiles are not used). After a while I get calls from users saying that they are not able to save documents because there is no drive space available. I know that the user can move/redirect their own ?My Documents? folder to another location, but is there a way (local Group Policy, registry edit, or script) to have the system redirect the ?My Documents? folder for all local users to the much larger D partition? And to make the D partition the default for all new/future users. The added benefit would be that if the OS bites the big, you could reinstall it without affecting the user data.
