I forgot that you can do that with Windows. That should work. I've
about run out of cycles for backup/restore testing so I'm not sure if
I'll get a chance to try it, but if I do I'll post the results.

I didn't see anything, but I'll look when I get a chance. For us it
isn't currently all that big a deal, and we may even be able to handle
it through a change to the process: as the last step before rebooting,
go back and assign that partition to E: again.
BTW: the machine that I have been testing on is a clone of our Domain
Controller / Exchange Server. With the exception of the minor glitches
mentioned above, after the restore the system came up just fine and
users were able to log in and get their at their email. I'm still not
an expert with Windows (and I intend to keep it that way), but are there
other potential issues with restoring Domain Controllers / Exchange
Servers / other MS servers (other than data-loss between backup and
crash) that I've missed?
