Hacking Microsoft Networks

[Angela]

My experience of hacking at the moment is limited to simple brute force,
password guessing (with which I had a lot of sucsess).
But I want to hack a Microsoft Windows 95 Network.  
And I really need your help.

P.S.  Do I have to get past the PWL file? How?
And what will happen if I just delete the file?
