Running a MineCraft Server

[ZWarrior]

1) create a folder. We'll call it C:\Minecraft
2) download minecraft_server.jar from Minecraft.net to the folder you created.
3) create a text file in that folder. Call it start_server.bat
4) open the text file and put the following code in the file.

@echo off
java -Xmx3072M -Xms3072M -jar minecraft_server.jar

5) save the file
6) create new file called server.properties and edit in notepad.
