Win XP admin password recovery tool needed

[autopilot]

Hey.

I work in a school and we have a couple of Win XP (SP3) PC's with admin accounts we cant access due to the kids finding the password, changing it then 'forgetting' it.

I did have a linux boot CD that blanked the admin password, but i lost it and cant remember where i got it from. Can anyone recommend anything they have used please? Thanks.

i've used ophcrack, and another one but i'm not sure what it is called.

edit: Ophcrack isn't what i was after

i'm looking for the other

edit2: here it is: http://pogostick.net/~pnh/ntpasswd/ works perfectly once you find your way around

ERD2005 from Winternals. Not sure whether it is still available, but locksmith works a treat.

Thanks mate. Unfortunately i tried that one yesterday but wont work (missing controller driver). Known issue, no work around.

Ah yes Locksmith. Locksmith was available as a free download on its own, but i cant find anywhere to download it. Anyone?

If you can boot a knoppix live cd (or any other linux live cd for that matter) on the box, then you can use the pre-compiled binary rather than the boot cd. it's cli based work, but doesn't take long to work out.

EDIT: Also, I use that tool on VMs a fair bit and it's worth reloading the drivers *twice*, as for some reason the boot script doesn't recognise the virtual scsi device until the second rescan.
