I would've if I knew who it was. The problem is this dorm is big and no body knows who that bastard is.

Well, not sure about all the network secuirty there, but a good start would be finding the IP range for the dorm and start looking at the traffic for each one.
etherape would help here. Even comes with pretty graphs.
Once you know the IP of the person, there area a variety of things you can do to determine who they might be. There are also a variety of things you can do to murder their connection without knowing who they are.
I don't think there's a windows port of Etherape. You'll probably have to get Ethereal and eyeball the output.
Once you have the IP, you'll need to gather information. E.g.: portmap it, traceroute it (just because), take a look at it through Network Neighbourhood, etc. This usually will give you all kinds of information to go with, and if you're really lucky maybe even a name or an open share.
If you can't find the person, but you're on the same segment as the poor sod, you can murder his connection with a tcp reset attack, or maybe do some ARP cache poisoning. And that's just the beginning.

a really simple trick if your on a half duplex connection(IE shitty hub) is to just ping flood his pc with the largest ping size windows will allow, open as many dos windows as you possibly can.
its simple, and it will slow his connection down to pathetic speeds if you do it enough. this is assuming he's even there, and not just downloading a ton of shit from torrents or ftp's while he's out banging his gf :P

Thank you for your support. It kind of sounds hard for me but I will try my best to kill that retard's connection.

QoS on the router = instant HTTP priority.

damn I don't know why but after I capture for 10min, when I try to save it, it causes an error. let me try a little bit more....
Unless you're the admin of the network, you won't be able to change anything like this. Bitch at your network admin? Layer 7 QoS is a (mostly) solved problem.

how do can I portmap and traceroute it? And how can I do tcp reset and ARP poisoning? Sorry for asking bunch of question. I'm too new to this program :(

You'll need a portmapper. The best-known one is NMap, but it's primarily a unix proggie. The windows port used to be dog slow, but maybe it has improved. You'll need to download it, then type something like "nmap -p1- <ip>", where <ip> is your target's IP.
Traceroute is easy. Open a dos window and type "tracert <ip>". It'll show you the number of hops between you and your target. In all likelihood you'll only get one hop, in which case the target is on the same network segment as you.
TCP reset and ARP poisoning might be a bit beyond windows, I think. There are unix programs that do it, but I don't know if they run on windows. I do know there's some TCP reset code for windows floating around, but you'll need a compiler.
