...you don't know whats the difference between cable connection ans ISDN ...you don't know about that network architecture ...you know almost nothing and you want to "hack" into a station for a thrill ...ok ...i think i found myself a few years ago...
the thing is that if i'm gonna give you a litle source code for breaking into an IDONKNOWHATNETWORK LAN beside u probably won't be able to adapt it and compile it (excluding the fact that there isn't such program) after you would run it and brake into what satisfaction you gonna have ... you gonna tell the sys admin about his breach ...or your friends about the skills you don't have?
this is not the way my friend. What you should do is go on www.google.com or a bookstore and then buy books about NT os and other OSs then about networks ...then about security of the networks and this would be much more effective...and belive me you'll find much more interesting things then using stupid code wich you don't know what it does for something so ABSTRACT to you as a network or a box in that network...
after you gonna learn about the network ...the os you will be probably able to hack into it ..but you won't find that attraction for this anymore ...other things will be of a bigger importance for you
good luck
