ERD for Windows 2000

Any idea, how can I do this command ‘rdisk /s’ in Windows 2000. Because I used this command for all my NT 4 servers to update the local ‘systemroot\repair’ folder then copy over to another specific server for backup purpose. Of course, I’m using this ‘at’ command and everything done automatically. I do not want to use this ‘regback’ & ‘regrest’, unless I have no choice.
