Lets just start off by saying that I am a major noob but I realize the consequences can be jail time.
Background info
One day at work I had accidentally forgotten to punch out when I went on break. When I came back I realized that I was on the clock during my break. Obviously I went to tell my manager so I wouldn't get in trouble. We were in the office when I told him and he said "no problem" and turned to the computer to fix it. He was logging into what I assume was the sysadmin account because he had the ability to manually change my time punch to fix my mistake. Now realizing the power his account has, I wish I had looked at his hands when he was typing the password. But since that day, when we are slow(all the time) I think about that computer; I mean its right there. I could actually walk just 15 feet from my spot on the grill line to the office and literally press the power button shutting down this system.(I wouldn't do this because I have no idea what would happen, probably fired) its just sitting in there, with open usb ports too. Like I said, I am a noob. I have no idea what I could do with this, but I want to break into this system really bad, just for the thrill. I want to do this just to see if I can and to learn how safe my job is.
The system is running Windows server 2003
EDIT: The other system is in fact i2i video surveillance system
There is another computer on the desk, but I am not completely sure about the possibilities on that one, I'm not even sure if its connected to the main one yet but it displays all the security cameras and it says "i2i systems" if I remember correctly.
Please share some knowledge with me, I am a very curious noob.
