That isnt hard at all but if youre cough you can end some years in jail...thats for sure more dangerous than sending some packets to the machine, youre hacking a private computer with private data in it. Argh..and by the way, most companies are smart enough to run their servers on Linux , BSD etc... Once you hack a linux's firewalls and make a special trojan for it, let me know, so i can call the local police department ...
Anyways...if you manage to find a server running on a windows OS, thats easy to hard. Just block a part of the bandwidth, use the l2 protocol to send a trojan (be smart enough to crypt it up, so anitiviruses wont detect it :p...or make it your own), stop attacking the connection so they will think that was just smth from the ISP, and then start playing(again, be smart enough and make it they wont observe...those ppl are there for something and they arent blind :p). Also make some backups of the trojan in the heart-files of the server...like the DB or a key file of the Operation System.
