To setup your own dedicated server. A quick and dirty guide.
You need the steam client on your server box (some people need to run as admin). You can either install ASA Server using the Steam client or use SteamCMD with this command (If you dont know steamcmd just use the steam client.)
steamcmd.exe +force_install_dir c:(Where you want it installed) +login (Your Username) (Your Password) +app_update 2430930 validate +exit
Remove the () and enter your information.
Once you get the server installed, have the steam client running logged in to your account that has ASA and set it to offline mode. (Click steam at the top left and click go offline)
Create a .bat file with this code and put it into the same folder as the ArkAscendedServer.exe.
start ArkAscendedServer.exe "TheIsland_WP?SessionName=(Name you want your server)?AltSaveDirectoryName=(Save file name, do not put an actual directory here no spaces.)?listen?ServerPassword=(server password)?Port=7775?QueryPort=27030?" -NoTransferFromFiltering -NoBattlEye
Remove the () and add your information
Run it once to get your default server files and wait a few minutes. Close the server program after.
Open the game on your PC and create a non-dedicated game using the settings you would like to have on your server. Once you start the non-dedicated server it creates the ini files you can use to change settings on your server. Copy the gameusersettings.ini and game.ini file from \ARK Survival Ascended\ShooterGame\Saved\Config\Windows on your PC and put it into the folder on your server \ShooterGame\Saved\Config\WindowsServer.
Run the server program again and it should start with your custom settings. Make sure your ports are forwarded (I cannot help you with this you need to know how or figure it out yourself) and then join the server and play!
This is what worked for me, I do not take responsibility for anything if it doesn't work. If you need more help ask in the channel and hopefully someone can help you.
