I havent been able to do it through DOS, however from NT Backup I have been able to install a fresh copy of the Windows OS from CD ( after first making sure that the backup data is on an external media like external or 2nd hard drive to avoid total data loss!! ) then from the clean build use the Windows NT Backup to restore this backup overtop of the clean build to get you back to where you want to be. System then just needs to be restarted after restore and you should be all set.
Biggest compatability hurdle for DOS and Windows today is DOS's inability of accessing NTFS drives

Only tools out there to access NTFS drives at a DOS level are actually built on LINUX
