A. From the Start Menu, select Run, and type RDISK. Click on Update Repair Info. It will then recreate the repair information stored in the winnt\repair directory. It will ask if you want to create a repair disk, insert a blank formatted disk and select Yes. RDISK /S updates the information in the %systemroot%/repair and also the SAM and SECURITY keys. Permissions on the repair should be strict as a user with access to the files could create a repair disk and use it to crack the system passwords.
