How to Fix “A Required Network Service Has Failed” Error: A Comprehensive Guide

Experiencing the dreaded “A Required Network Service Has Failed” error can be incredibly frustrating, especially when you’re eager to jump into your favorite online game. This error, commonly encountered in games like Call of Duty: Modern Warfare and Warzone, indicates a problem with your connection to the game’s servers or a disruption in your network. Here’s a detailed breakdown of how to troubleshoot and fix this issue:

Direct Solutions:

1. Restart Your Game and System: This is the most basic but often effective first step. Close the game completely, and then restart your PC or console. This can clear temporary glitches that might be causing the error.

2. Check Your Internet Connection: A stable and reliable internet connection is crucial. Ensure your internet is working correctly by browsing the web or running a speed test. A slow or intermittent connection can trigger this error.

3. Verify Server Status: Before diving into more complex solutions, check the game’s server status. Visit the official game website or social media channels to see if there are any known outages or maintenance periods. If the servers are down, there’s nothing you can do but wait.

4. Update the Game: Outdated game files can lead to connectivity issues. Make sure your game is updated to the latest version. Most platforms will automatically download updates, but it’s worth manually checking for updates in your game library.

5. Restart Your Router and Modem: This simple step can resolve many network-related problems. Unplug your router and modem from the power outlet, wait about 30 seconds, and then plug them back in. Allow a few minutes for them to fully restart.

6. Flush DNS and Reset Winsock: These commands reset your network settings. Open Command Prompt as an administrator and enter the following commands one by one, pressing Enter after each:

   • ipconfig /flushdns
   • ipconfig /registerdns
   • ipconfig /release
   • ipconfig /renew
   • netsh winsock reset

   After running these commands, restart your PC.

7. Check Firewall and Antivirus Settings: Your firewall or antivirus software might be blocking the game’s access to the internet. Ensure that the game is allowed through your firewall and antivirus. You might need to add an exception for the game’s executable file.

8. Disable Crossplay (If Applicable): In some cases, crossplay settings can cause connectivity issues. Try disabling crossplay in the game settings to see if it resolves the error.

9. Verify Game File Integrity: Corrupted game files can cause various issues, including network errors. Use the platform’s built-in tool to verify the integrity of your game files (e.g., “Scan and Repair” in Battle.net, “Verify Integrity of Game Files” in Steam).

10. Check for Other Bandwidth-Heavy Applications: Other programs consuming significant bandwidth can interfere with your game’s connection. Close any unnecessary applications, such as streaming services or large downloads, while playing.
