I`ll create a bootable iso you can burn to cd and use if you`d like. (it`s small)

1. Change the boot order - how will depend on what BIOS they use.  Change it so that you can intercept the boot order (ie prioritize booting from a floppy over booting from the harddrive)
   
2. Once you'd done that, you'll need to make the boot floppy or USB - you'll need to include the necessary tools (from memory, mainly NTFSDOS and SAMDUMP)
   
3. Boot up with your boot medium, run NTFSDOS so that you can access the harddrives from DOS, then use SAMDUMP to dump the password hashes
   
4. Restart the computer - if you want, you can restore the BIOS boot order
   
5. That's all you do with the target computer - if done correctly, no-one should know that you've done anything to it.  Go to http://loginrecovery.com/ and upload your password hash file
   
6. Wait about 2 days for it to process it - once done, it'll give you the admin password.

This is a permission issue. If the net view command fails with a "System error 5 has occurred. Access is denied." message, 1) make sure you are logged on using an account that has permission to view the shares on the remote computer.
2)  Need to cache credential: logon the same username and password on both computers or use net net use \\computername /user:username command.
3) Make sure the Netlogon service is running.
