Hello,

I am trying to find a free tool that lets me to reset the administrator password for my Windows XP SP2. Everyone seems to point to the Bootable Linux CD which I download from this website http://home.eunet.no/~pnordahl/ntpasswd/bootdisk.html

However when I try to run the CD I always get the Failure to write to DISK and therefore any changes made to the password are never saved.

Are there any other solutions that really work and will not damage on install anything in my PC.

Thanks in advance

You might have to remount the Windows XP disk so that it has the read/write.

What does it mean to be "Always On"?

Is your cloud always on? With an Always On cloud you won't have to worry about downtime for maintenance or software application code updates, ensuring that your bottom line isn't affected.

Thanks, I got your email but the first solution is the one I mention before and it does not work because I do not have read/write access to my c drive.

The second solution does not work either because I am not an admin user in my PC and I am not allowed to install any new applications.

I will keep trying.

When you boot the system with the linux Cd.  Run mount to see whether the /dev/hda is mounted as read/write or read only.  This is likely the issue you ran into.

You need to unmount the C: drive and remount it using:
mount -t ntfs /dev/hda /mnt or something similar.
once it is mounted with read/write access you should be fine.
Have you had a chance to look and try the directions at the petri link?

We use ERD by sysinternals.  I heard a rumor that you can find it in a torrent file.

The Ultimate Boot CD has the same application to reset the password but it is initiated from a different menu. Still the same error about read only drive.

I checked the Petri site but I did not find a solution. How should remount the disk? I only have this bootable cd with linux and there is not command prompt, it follows the script I believe...

I will check the ERD now and see if that works for me.

"The Ultimate Boot CD has the same application to reset the password but it is initiated from a different menu." I linked to UBCD4Win -- completely different from UBCD. Please go to link.

Willcomp, not sure if I am following you. This is what I do.

I restart the system using the UBCD v4.1.1 -> Filesystem Tools -> NTFS Tools -> Offline NT Password & Registry Editor 070409. Then the application starts I get the read only error...

Should I do something different?

That's UBCD not UBCD4Win which is a completely different boot disk based on Bart PE. Go to the link!
