Repair  PathtoERFiles PathtoNTSourceFiles  /NoConfirm /RepairStartup /Registry /RepairFiles

Description:        Replaces the NT4 Emergency Repair Process Screens

Arguments:

PathtoERFiles

    Path to the Emergency Repair Disk Files (Setup.log, autoexec.nt, config.nt).
    If this is not specified, the default is to prompt the user with 2 choices:
    Use a floppy, or use the repair info stored in %windir%\repair

PathtoNTSourceFiles

    Path to the NT CD source files.  By default, this is the CD-ROM if not
    specified. [Kartik Raghavan]  This path does not need to be specified if
    you are repairing the registry and/or the Startup environment.

NoConfirm

    Replace all files in setup.log whose checksums do not match without
    prompting the user.  By default, the user is prompted for each file that
    is different and whether to replace or leave intact.

Registry

    Replace all the registry files in %windir%\system32\config with the original
    copy of the registry saved after setup and located in %windir%\repair.

RepairStartup

    Repair the startup environment / bootfiles/bootsector.
    (This may already be covered in another cmd--Wes?)

Repair Files

    Compares the checksums of the files listed in setup.log to what's
    on system.  If a file doesn't match, then the user is prompted to replace
    the file with the one from the NT Source Files.  The user is not prompted
    if the /NoConfirm switch is specified.

Usage:

    Repair a:\ d:\i386 /RepairStartup
    Repair
