When your PC starts throwing you enigmatic error codes like "627 (0x273) - ERROR_RANGE_LIST_CONFLICT," it can feel like the digital equivalent of trying to read hieroglyphs while stranded in the desert. This Windows system error often comes bundled with the message, “The range could not be added to the range list because of a conflict,” which doesn't exactly scream “easily fixable.” Let’s decode the situation and tackle this error like seasoned troubleshooters.

What Is ERROR_RANGE_LIST_CONFLICT (627/0x273)?​

This error typically occurs due to one (or a combination) of the following problems:

• Missing permissions: Certain files or folders don't grant users or the system adequate control.
• Corrupted system files: Key files required for smooth system operation could be damaged or misplaced.
• Misconfigured network settings: Network properties or conflicting IP ranges can cause chaos.
• Third-party software conflicts: Installed or recently updated apps may be clashing with necessary OS functions.

Before jumping into specific fixes, a few housekeeping steps are worth trying:

• Perform a simple system restart.
• Ensure your Windows updates are installed.
• Temporarily disable third-party security or “performance optimization” software.

If you’ve done the basics and the issue persists, it’s time for some deeper troubleshooting.

5 Methods to Fix ERROR_RANGE_LIST_CONFLICT on Windows​

1. Repair Corrupted System Files (The Fortify-Chains Approach)​

Corrupted system files are a leading cause of many Windows mishaps. Microsoft's built-in tools, DISM (Deployment Image Servicing and Management) and SFC (System File Checker), can come to the rescue here. Think of them as digital medics patching up scars and bruises on your OS.
Steps:

• Press Windows + S and type Command Prompt.
• Right-click on Command Prompt and select Run as Administrator.
• Enter the following commands one by one, pressing Enter after each:
• DISM /Online /Cleanup-Image /CheckHealth
• DISM /Online /Cleanup-Image /ScanHealth
• DISM /Online /Cleanup-Image /RestoreHealth
• After DISM finishes, run the System File Checker:
• sfc /scannow
• Once scanning and repair are complete, restart your PC.

Why It Works: DISM repairs the Windows image, while SFC cross-checks existing system files against cached copies. Any problem children are replaced.

2. Check Permissions on Files and Folders​

Ever tried getting into a concert without the right pass? Windows is no different – and when critical files have limited permissions, it can lead to errors like this one.
Steps to Fix Missing Permissions:

• Right-click on the problematic file or folder and select Properties.
• Switch to the Security tab.
• Select Advanced and click Change next to the Owner label.
• Enter Everyone in the text field, click Check Names, and select OK.
• Tick the boxes for:
• Replace owner on subcontainers and objects.
• Replace all child object permission entries with inheritable permission entries.
• Return to the Security tab and click Edit under Group/User Names.
• Add Everyone again and enable Full Control permissions.

Why It Works: Missing or restricted permissions lock the OS out of certain operations, triggering errors. By granting "Everyone" access to the file, you hopefully clear the bottleneck.

3. Reset Network Settings​

Misconfigured network settings can also trigger this error. Resetting these configurations often solves the problem without requiring a PhD in TCP/IP.
Steps:

• Open Settings using Windows + I.
• Go to Network & Internet > Advanced Network Settings > Network reset.
• Click Reset Now, then confirm when prompted.
• Reboot your PC to apply these changes.

What Happens During Reset: This action restores your network configurations to their default values (like a factory reset for your network stack). It’s especially handy if the problem is tied to funky IP configurations or conflicting ranges.

4. Uninstall Conflicting Apps​

The "one rotten apple spoils the bunch" trope applies here. Apps installed, updated, or tinkered around the time you first encountered this error might be the culprits.
Steps to Uninstall Potential Troublemakers:

• Press Windows + R, type appwiz.cpl, and hit Enter.
• Look for programs installed around the trigger point of the error.
• Select a program and hit Uninstall.
• Follow any additional onscreen instructions and restart your PC.

Advanced Cleanup Tip:
If uninstalling the app doesn’t resolve the issue, use a dedicated uninstaller tool to clear out any leftover files or registry entries tied to the problematic application.

---

5. Perform a System Restore (The Windows Time Machine)​

When all else fails, sometimes winding the clock back solves the problem. A system restore point reinstates your PC to a previous state when things ran smoothly.
Steps:

• Press Windows + S, type Create a restore point, and hit Enter.
• Click System Restore and select Choose a different restore point, if available.
• Select a date and time before the error began.
• Click Next > Finish, and let the restoration process complete.

Key Reminder: System Restore reverses misconfigurations, but doesn’t affect personal data unless explicitly tied to problematic apps.

The Last Resort: Reinstalling Windows​

If none of the above worked, a complete reinstallation of Windows might be the clean slate your system needs. However, this is usually overkill – most users will find success with granting full folder ownership, repairing files, or resetting their network settings.

Key Summary​

• The 627 (0x273) error typically arises due to permission problems, corrupted files, network config woes, or auxiliary app conflicts.
• Simple Steps First: Restart, check for updates, and temporarily disable overprotective antivirus.
• Detailed Fixes: Use tools like DISM and SFC, reset network settings, reconfigure permissions, uninstall conflicting apps, and revert to a stable restore point.
