RESOLUTION
To resolve this issue, either restore or replace the SAM
file.
Note You cannot use the repair process or the recovery console to
resolve this issue. These methods require authentication, which cannot occur if
the SAM file is corrupted or missing.
To resolve this issue, use one
of the following methods.
Method 1: Restore the SAM File from Backup
If you used the Backup utility in Windows XP to back up the
system state, you can restore the SAM (and all other registry settings) from
the disk or archived copy by using the Restore Wizard or the Automated System
Recovery Wizard.

Method 2: Copy the SAM File from the Repair Folder
If you cannot restore the SAM file by using the Windows Backup
utility, copy the SAM file from the following location
and paste it to this location:
C:\WINDOWS\system32\config
Note When you do this, you will lose all accounts or groups that had
been created. You will also need credentials that were valid at the time that
the ASR was run. This will restore the SAM back to the last instance that
Automated System Recovery (ASR) was run, or to when the system was first
installed. To do this, follow these steps:
- Do either of the following:
- Start the computer from another operating system (if
you have a multiple-boot system).
Note If Windows XP is installed on an NTFS file system drive, you must
start the computer from an operating system that can access the NTFS drive (for
example, Microsoft Windows 2000 or Microsoft Windows NT). If Windows is
installed on a FAT32 drive, you can start the computer by using Microsoft
Windows Millennium Edition (Me) or Microsoft Windows 98.
-or - Perform a parallel installation of Windows XP, and then
start the computer from the parallel installation.

Method 3: Reinstall Windows XP
If you cannot restore the SAM file by using either Method 1 or
Method 2, you must reinstall Windows XP to replace the SAM file.

replaced. This method may require that you reformat the partition that Windows
XP is installed to. Before you continue with this method, make sure that you

Windows XP to a different partition than where Windows is currently installed.
