Introduction So, I guess you've heard about the new thing released by us (alterIWnet) that brings the most-requested missing feature in MW2 to, well, MW2? It took quite a lot of researching, and some say it may be late, but anyway, it's finally here.
As you're reading this guide, I guess you're interested in setting up one of those, what do you call it, 'dedicated servers'? Even though most of the process is similar to previous titles in the Call of Duty series, there are some specific things that differ, and obviously having a guide is better than having none.
Requirements
* A network connection with enough bandwidth to host a MW2 server (1 megabit upstream is recommended)
* A computer running Windows XP or higher (or Wine, see the specific chapter)
* 512 MB of RAM (though 1 GB+ would be better, a server process takes around 350 MB)
* A not-too-slow CPU (though any CPU would be okay, I'd guess)
* The Modern Warfare 2 game (with the aIW-specific files added, can be a copy of your normal aIW game)
* All the usual dependencies for MW2/alterIWnet (likely including DirectX files)
* A GPU with at least Shader Model 3.0 -- whoa, isn't it a dedicated server?
* Some knowledge about console commands
The guide
1. Firstly, you need to have the usual alterIWnet client files installed on a MW2 installation. If you're using a dedicated server (or VPS) hosted somewhere, you can also ZIP and upload the usual alterIWnet installation you play with. Note that you will not be able to play with the dedicated server at all. 
2. Now, extract and overwrite the files from the dedicated server package to your MW2 installation on the system you're planning to run the dedicated server on.
3. As I forgot to pack it in with the package, make a copy of your iw4mp.dat and name it iw4.exe. Also, optionally, download content/nulliwd.7z (contains empty IWD files, make sure you don't accidentally your originals!)
4. Make a server configuration file (see the chapter 'Configuration file' for more information). You can skip this step, but it's a lot easier to maintain the server with a configuration file. 
5. On Windows, you can make a shortcut to run the server by hand -- to do this, make a shortcut to 'iw4.exe', open the properties for it, and add the launch options (see the 'Launching' chapter) to the 'Target' input field. For other systems or methods of launching, see the 'Launching' chapter as well.
6. Run the server using the method you chose for launching it.
7. To see if everything works correctly, run the alterIWnet client (make sure that, if on the same computer, the server is not using port 28960) and, in the console, use 'connect [IP]:28960', replacing 28960 with the specific port for the server. Also, 127.0.0.1 won't work locally, so use the IP assigned to your network card.
Launching
Windows (GUI):
Add launch parameters to the shortcut, so that it looks like this:
iw4.exe +set party_maxplayers 18 +set net_port 28960 +exec server.cfg +map mp_rust +map_rotate
