How to reset admin password with Guardianedge encryption

Posted on 2011-04-25

I have a very old laptop that is on it's last leg. There is software installed on this laptop that I no longer have the disks or keys for, so reinstallation to a fresh system is not an option, I must move this installation to new hardware.

The laptop is encrypted with Guardianedge so I made a raw sector-by-sector image with Acronis and then installed on new computer. Worked perfectly. Except for one little problem.

On first login on the new system the OS (Windows XP SP3) began to recognize and install drivers for the new hardware at which time I was prompted for the Administrator password. Which I don't remember.

I have my user password for Guardianedge and my user account password, but I don't recall the admin passwords for either. It's been nearly 5 years since I've needed them.

I can't decrypt the drive so, typical password reset options won't work. And I don't know the admin password so I can't install the drivers on the new system. I'm stuck.

How can I reset the admin password in this situation? I really don't have $3500 for new software licences, please help!

    I've used GuardianEdge in the past as a system admin and one of the guarantees we got from the supplier is that if a laptop is stolen no user will be able to decrypt the drive unless there the government which will still take sometime, without the admin password your permanently stuck dude.

    I've been doing some reading and it seems that Guardianedge, and all other software based disk encryption, store the encryption keys in memory. Once I am logged in, it would seem I just need a memory dump to retrieve the keys which can be used to decrypt the drive.

    This is a huge hassle though, and this isnt a procedure I'm familiar with. I have a deadline to hit and I need to migrate this to the new hardware asap.

    Is there a quicker way to get this done? I just need to get a handful of drivers installed... frustrating...

    With the userpassword for windows: why don't you move all userdata to an usb drive and install a fresh unencrypted windows xp on the laptop?

    If you need full disk encryption, you can use truecrypt or drivecrypt. Drivecrypt from comes with full support for €125.
