How to Setup Space Engineers Dedicated Server on Windows server 2022

Hosting a Space Engineers dedicated server on Windows Server 2022 allows you to create a stable multiplayer environment where you control all settings, mods, and performance tuning.

Step 1: Download SteamCMD

First, you need SteamCMD, the command-line tool from Valve, to install and update the Space Engineers server files. Download SteamCMD directly from the official Valve website and extract it to a folder such as C:\SteamCMD:

mkdir C:\SteamCMD
cd C:\SteamCMD

Then place the steamcmd.exe file inside this directory and run it once to initialize.

Step 2: Install Space Engineers Dedicated Server Files

With SteamCMD installed, log in anonymously and download the Space Engineers server application:

steamcmd +login anonymous +app_update 298740 validate +quit

This will download the dedicated server files into your chosen directory (usually under C:\SteamCMD\steamapps\common\SpaceEngineersDedicatedServer).

Step 3: Configure the Dedicated Server

After installation, open the Space Engineers Dedicated Server tool. You can find it inside the installation directory or access it through a shortcut created in the Start Menu. From here, configure your server:

• Set the world name and save location.
  
• Adjust maximum players and server names.
  
• Enable or disable mods, plugins, and auto-save.
• Configure IP address and port (default: 27016).

Save your configuration once the settings are adjusted.

Step 4: Allow Firewall and Port Access

For players to connect, ensure Windows Firewall allows the server to communicate. Open the required ports in Windows Server 2022:

• TCP/UDP 27016 (default Space Engineers port)
  
• Any additional ports if configured in your setup

   

Use Windows Defender Firewall to add an Inbound Rule for these ports. This step ensures remote users can connect to your server.

Step 5: Start the Space Engineers Dedicated Server

Once configuration and firewall settings are complete, launch the server from the Dedicated Server Configurator or by running the executable in the install folder. The console will show the server status, and if everything is configured correctly, your server will appear in the game’s Server List.

Optional Step: Set the Server to Start Automatically

If you want your Space Engineers dedicated server to run after system restarts, set it up as a Windows Service or use the built-in Task Scheduler to auto-start the executable on boot. This ensures high availability without requiring manual restarts.
