User manual WINTERNALS ERD COMMANDER PRO 1.03

[. . . ] It is a command-line shell that runs off of a set of NT boot disks giving you full access to non-bootable NT systems with a robust set of familiar command-line file manipulation tools. Because ERD Commander relies on a standard set of NT boot floppies, any NT system is accessible, and because ERD Commander runs on top of NT, all NT file systems, including FAT, NTFS, and CDFS are visible. ERD Commander has no reliance on data located on a system's hard disk for it to boot and run ­ NT is actually booted on the floppies. Windows NT does not even have to be present on the computer in order to use ERD Commander to access the computer's drives. 1. 2 Upgrading to ERD Commander Professional ERD Commander Professional Edition augments the basic set of ERD Commander functions with advanced features and additional commands.

Winternals Software LP Page 6 ERD Commander Version 1. 03 3 Starting ERD Commander 3. 1 Booting Up After the disks are loaded, a stripped­down version of Windows NT will start, displaying the familiar boot­time Blue Screen that presents the NT version number, system memory size, and number of processors present. ERD Commander then starts automatically and enters a command­line environment nearly identical to the one NT implements in Command­Prompt. 3. 2 Sample Screen Figure 3-1 is a presentation of what a typical display looks like after ERD Commander has started. ERD Commander presents information on the disk drives that are recognized and the drive letters it has assigned for them. Volume name, file system type, and drive size data should help you identify particular drives.

Syntax Switches ACCESS [[drive][path]filename] [/S] /S Processes files in all subdirectories in the specified path This command is a custom ERD Commander command. It is possible to render a NT system unbootable by inadvertently applying security restrictions to NTFS files or directories that prevent NT from loading files it requires. The ACCESS command will add a security entry to the security attributes of specified files or directories which gives the Everyone group full access. The Everyone group includes all groups and accounts, so this is the most permissive security setting possible. If the file or directory specified is inaccessible because the System account or Administrators group is denied access, ERD Commander will first take ownership for the Administrators group. This allows it to then modify the security settings to give Everyone full access. The command can even be applied to root directories of drives that have been totally locked down. Such drives will show up in the drive mapping as having a file system type of "???". [. . . ] This occurs when a driver necessary to access your floppy disk is not installed and when using PCMCIA-based floppy drives for laptops. To correct this, manually install the PCMCIA driver on the ERD Commander diskettes. You must specify the /H switch to copy system and hidden files, and the /R switch if you wish to overwrite read-only files. How can I edit files on the machine after I've booted with ERD Commander?
