Server Setup

Batch Script

Server Start .bat File

Launch your DayZ server with the correct settings, mods, and parameters using a batch file. Automate startup and ensure consistent configuration every time.

Overview

A server start .bat (batch) file is a Windows script that launches your DayZ server with the correct settings. It ensures consistent startup with every launch, automatic mod loading, and reduced human error by eliminating manual command entry.

Important: Always right-click your .bat file and select "Run as administrator" to prevent permission errors.

Basic .bat File

Copy this into a new text file, save with a .bat extension, and place in your DayZ server directory.

@echo off
title DayZ Server

:: Server Configuration
set SERVER_PORT=2302
set CONFIG_FILE=serverDZ.cfg
set PROFILES_FOLDER=ServerProfile

:: Start the server
start "DayZ Server" /min "DayZServer_x64.exe" ^
    -config=%CONFIG_FILE% ^
    -port=%SERVER_PORT% ^
    -profiles=%PROFILES_FOLDER% ^
    -dologs ^
    -adminlog ^
    -netlog ^
    -freezecheck

echo Server started successfully!
pause

Advanced Configuration with Mods

Add the -mod and -servermod parameters to load mods. Mod folder names are case-sensitive and must match exactly.

@echo off
title DayZ Server with Mods

:: Server Configuration
set SERVER_PORT=2302
set CONFIG_FILE=serverDZ.cfg
set PROFILES_FOLDER=ServerProfile

:: Mod Configuration (semicolon separated, no spaces)
set MOD_LIST=@CF;@Community-Online-Tools;@VPPAdminTools

:: Start the server with mods
start "DayZ Server" /min "DayZServer_x64.exe" ^
    -config=%CONFIG_FILE% ^
    -port=%SERVER_PORT% ^
    -profiles=%PROFILES_FOLDER% ^
    -dologs ^
    -adminlog ^
    -netlog ^
    -freezecheck ^
    -mod=%MOD_LIST% ^
    -servermod=@CF ^
    -bepath=battleye

echo Server with mods started!
pause

Auto-Restart Script

Keep your server online 24/7 with an auto-restart script. If the server crashes, it automatically restarts after a short delay.

@echo off
title DayZ Server Auto-Restart

set CONFIG_FILE=serverDZ.cfg
set PROFILES_FOLDER=ServerProfile
set MOD_LIST=@CF;@Community-Online-Tools

:restart
echo Starting DayZ Server... %date% %time%

"DayZServer_x64.exe" ^
    -config=%CONFIG_FILE% ^
    -profiles=%PROFILES_FOLDER% ^
    -dologs -adminlog -netlog -freezecheck ^
    -mod=%MOD_LIST%

echo Server stopped. Restarting in 10 seconds...
timeout /t 10 /nobreak
goto restart

Troubleshooting

Server Won't Start

Verify all file paths are correct, serverDZ.cfg exists, and you're running as administrator. Check that all required mods are installed.

Mods Not Loading

Mod folder names are case-sensitive. Use semicolons to separate mods with no spaces. Load mods one by one to identify problematic ones.

Performance Issues

Monitor CPU and memory usage. Reduce mod count if experiencing long load times. Use an SSD for faster file access.

Best Practices

Avoid

Spaces in mod names or paths
Incorrect case in mod folder names
Missing required configuration files
Running without administrator privileges

Pro Tips

Use Windows Task Scheduler to automatically start your server on system boot. Create separate .bat files for different server configurations (vanilla, modded, test). Keep a backup of working .bat files before making changes.
