    – Apologies in advance for long post.


    I’ve looked all over the internet, and throughout this site and forums and I’m beginning to think this is a lost cause. However, if anybody is able to suggest anything which may help here, it would be greatly appreciated.

    Basically, we were given a very old ex-work laptop from my housemate’s father. It’s a Toshiba Tecra 740CDT, running Windows NT4.0 (build 1381) with Service pack 5. The bios is 6.50.

    It’s quite obviously “not the greatest machine in the world”, but we thought it would still potentially be useful as an extra computer for word processing, or maybe accessing the internet or something.

    The problem is that it’s basically useless without the admin password. You can’t install or change anything, set up any network connections etc.

    Logging on as a guest is no problem (it was “guest” / “guest”, and was written on a sticker stuck to the case).

    We’ve looked at various utilities which should be able to reset the admin password, though they all appear to need a floppy drive or to boot from CD (or an external USB drive).

    There isn’t a floppy drive, and though there is a CD-ROM drive, we cannot boot from it. The options for boot order in the bios only allows booting from primary or secondary floppy drives or hard drives.

    We don’t have an installation disc for NT, though we did have a Windows98 one, but again, it won’t boot from a CD at all.

    There’s no USB ports to try and boot from external drives, and though it has an ethernet card, it cannot be connected to the internet or our network because we need admin access to set this up.

    We also tried the various renaming tricks with the login / usrmgr / cmd files etc, but none of these have allowed us to do anything (it says it still requires an admin account to change anything).

    Are there any utilities which can run from a guest account, which will somehow find / locate / crack / change the admin password?

    Anything which uses an installer file of some sort is no use, as we need admin access to install any programs. It would need to be some form of standalone .exe or something.

    It doesn’t matter if the password finding utility would take several days to find anything. Time isn’t really an issue, as the machine is effectively useless at the moment.

    Alternatively, is there any method of changing / updating the bios to allow a boot from CD?

    There is no useful information and no programs stored on the computer, so it doesn’t matter if we have to erase anything or everything.

    If any more information is required about the computer / system etc, we’ll try and find out for you.

    If anyone has any suggestions at all, it would be greatly appreciated.
