Hello,

IMHO it is best to use the password cracker from http://home.eunet.no/~pnordahl/ntpasswd/
since it is a lot more easier, if you do use scisi HD you should download the scisi driver provided in that
web too i have try the software to crack the password in one of my w2k server using scisi HD
and it works like magic :) anyway it's up to you which path will you choose :)
