Updated March 23, 2017

"Call of Duty 4: Modern Warfare" (COD4) is a first-person shooter developed by Inifinity Ward and Activision. COD 4 is the fourth title in the long-running Call of Duty series. Unlike the previous versions of Call of Duty, COD 4 takes place in modern times. COD 4 contains a single-player campaign as well as a multiplayer option. Playing multiplayer online is a completely different experience from the single player campaign, because you can play in competitive matches against people all over the world, as long as you have online access. You can also create and start you own server for playing online.

Find the "Call of Duty 4" program directory folder on your computer system. Open you "C:" Drive, find and open the "Program Files" folder and open the "Activision" folder. Finally, open the "Call of Duty 4" folder. Send the "iw3mp.exe" executable to your Windows desktop.

+set dedicated 2 +set fs_game "mods/cod4_server" +set net_port 28960 +exec server.cfg +map_rotate

Click "Apply" and exit the options menu. Afterward, rename the "iw3mp.exe" file as "COD 4 Server."

Launch your Web browser. Type into the page's address bar and press the "Enter" key. You will be prompted to enter a username and password. Type "Admin" as your password and leave the username blank.

Click the "Status" tab and click "Local Network." Find your IP address and write down the last three digits of the address. Click the "Applications" tab. Create a new application. Name this new application "CoD4." Select a port range of 28960 to 28960. In the box named "Internal IP," input the last three digits of your IP address. Save recent settings and close the browser window.

Double-click the "COD 4 Server" desktop icon. The server will begin running. Locate your server on another PC running the game under the "Local" tab.
