Go to the website log in got to the minecraft beta 'download' section download the server software open file (extract if necessary I forgot if you have to) put it in a new folder labeled anything you want. click on the server.exe wait till it say done! then exit out of it go to your server properties open with notepad (in the same folder file just made) Change all info (true means yes false is no) when you get to server i.p go to command prompt,
( click start go to run then search 'cmd') Once in Command Prompt search 'ipconfig' without quotations and look for ip address. Go back to the server properties and enter your ip address exit out of it your port number will be 25565 (save!) then click server.exe again and server should run. Go to your minecraft game click multiplayer and enter in the ip adrress colan then 25565.
(i.e 123.123.1.1:25565) if you get on then it's running!
Hope this helps.
