The reason for this is to overcome the packet limitations the program sets up inorder to sotp spam and other crap from happening.
Voice, file transfer, et cetera take up a lot more bandwith then chatting. Instead of needing several OSx pipe lines to run a chat server, they(microsoft) tell the clients to directly connect to save bandwith.

next to each connection it will have a code to distinguish one connection from another ie. a web page you are looking at and the vice convo
The most I could get from this is, maybe you are thinking of the port numbers.
Quote:
the codes are listed on a microsoft webpage as well as many other dos basics web pages
Comlpetely lost you on these codes.

after getting your IP, there are websites that can track the ip to a location, so thats how he did that
The websites that do this are querying a database, it has nothing to do with tracking. And the physical location given has nothing to do with where the person using that IP address is, it is only to the place of business that registered that IP block. Example: I could sign up for a dial-up account in Belgium, dial into it across seas, ( I live in the US ). And if anyone ever 'tracked' me, it would appear that I live in Belgium.

Now tall of this takes less skill then playing most computer games
netstat -an and http://www.arin.net/whois/
No skill.

Well after getting your IP he could have easily ran a port scan on you, and found a nice little entrace
Open ports does not equal insecure, and it is not easy to 'enter'. An open port means that there is a service running that is accessible to the general public. AntiOnline has several open ports and there security is descent, http://www.hackus.co.za/ is hosting a contest as we speak, they have a server with 'open ports' and they are challening anyone to try and create a file on it.

from there he had access to your files ie the message archives. Not to difficut fo a thing to do.
Not difficult, ha. Only if he had happened to get a trojan from this 'friend', which I doubt. It is FAR from not difficult to do. If it is not difficult, could you please get that computer for me that they are offering as a reward http://www.hackus.co.za/

the defense. First and better then anyfire wall out there is common sense, ont Direct cnnect with people you dont know. this includes voice chat. Unfortunaly there are *******s out there that want to **** with you
I agree with you here.

second: get a good sftware firewall, look for specifics when purchasing one like one that does port checks and stuff to make sure your all sealed up
There are several freeware fire walls out there, and several that you do not have to 'purchase'. As for doing port checks, download a port scanner from our archives or hereand scan yourself.

I would also learn some basic networking stuff so you can mask your ip.
Masking IP addresses, at least doing a good job of it, is far beyond a basic networking skill.
Quote:
If your on static, cal your isp and request that you have a change of IP.
You would only be on static if you payed more. ISP's charge more for a static address, because it means that you will be hosting something, most likely, which would mean more of your bandwith will be used.

because it uses dhcp to connect me
DHCP or Dynamic Host Configuration Protocol, only dynamically assigns IP addresses. This has nothing to do with the connection that comes after, and also has nothing to do with 'new IPs'. I use a DHCP configured/controlled home network, and all of my IP addresses stay the same on my LAN because I have the router remember the clients that have been connected, and the IP it assigned it, and to keep them the same.
