NT4 need to find an accounts password any way to do this ?

Offline NT Password & Registry Editor will let you reset the password if that's good enough?
Can't you just log in with an administrator account instead, or ask the person who'se account it is?
I've used l0phtcrack to get the passwords before, or you could do it for free with Linux tools.

I'm guessing the account is for some sort of service.
Why can't you update the password in the dependent systems?
NT4 uses LMHASH to store passwords and LMHASH is weak, very weak.
You can brute force the password in several hours on a modern PC and hence recover the original without resetting it. LMHASH has a max password length of 14 ASCII characters, which equates to 2^94 possible passwords. However the hash also stores them in separate halves of 7 characters each (lol). What this means is you can attack each 7 character half in parallel and each half has a maximum of 2^46 possible passwords. You can easily brute force all the keyspace of a 2^46 character password on a modern PC
I would use with Cain & Abel or Ophcrack.
