Create a shortcut on the desktop to the CoDMP.exe and then add the following to the Target field in the properties (right-hand mouse click on the shortcut) window.

It will look something like this: Target: X:\Games\Call of Duty\CoDMP.exe

Add the following after CoDMP.exe and make sure these is a space between them:
+set dedicated 1 +exec server.cfg

+set dedicated 1
// make it a dedicated server (0=OFF 1=LAN 2=INTERNET)

+exec server.cfg
// Name of the server script you wish to execute. NOTE: Be sure it is in your X:\Call of Duty\main\ directory or it will not work

You now should have a shortcut named Call of Duty on your desktop with properties that look like this:

Target: X:\Games\Call of Duty\CoDMP.exe +set dedicated 1 +exec server.cfg

Now create a server.cfg file (create a text file with notepad/editpad whatever, and change the file extent ion to .cfg) script and put it into the Call of Duty\Main\ directory.

Next open a new file in said text editor copy and paste the following then save it:

GAME Types

Behind Enemy Lines (BEL)
This is a pseudo team based gametype, there are two teams, allies and axis, the hunters and the hunted. The hunted are a small group of players whose aim it is to survive being the hunted for as long as possible while killing as many as their predators. The hunters aim is to kill an allied player so they become the hunted.

seta scr_bel_alivepointtime "10" (seconds to get a point for staying alive as allied)
set scr_bel_scorelimit "50"
set scr_bel_timelimit "20" (in minutes)

Search and Destroy (SD)
The server is split into two teams, the attackers and defenders. The aim of the attacking team is to destroy one of the objectives (A or B) of the map by planting a bomb. The game can be won by either successfully planting, defending and destruction of the objective or by eliminating the opponent from the map.

set scr_sd_graceperiod "15" (in seconds)
set scr_sd_roundlength "10" (in minutes)
set scr_sd_roundlimit "2" (number of round wins per map)
set scr_sd_scorelimit "0"
set scr_sd_timelimit "15" (in minutes)

Retrieval (RE)
Retrieval is an objective based gametype similar to Search & Destroy in which the attackers goal is to steal one or more (depending on the map) of the objectives, typically radios or code books from the defending team. As you can guess, the goal of the defending team is to defend these objectives to the death.

set scr_re_graceperiod "15" (in seconds)
set scr_re_roundlength "10" (in minutes)
set scr_re_roundlimit "2" (number of round wins per map)
set scr_re_scorelimit "0"
set scr_re_showcarrier "0"
set scr_re_timelimit "15" (in minutes)

Headquarters (HQ)
Another team based gametype in which the server is split into two teams whose job is to capture, hold and defend the objective (normally a radio) from the other team. Every capture, and hold of an objective for a set time (default 45 seconds) results in points for the defending team.

set scr_hq_scorelimit "300"
set scr_hq_timelimit "25" (in minutes)
