What is Windows Error Code ERROR_106?
Before diving into solutions, it’s helpful to understand what ERROR_106 generally indicates. This error often corresponds to a “Transport endpoint is already connected” message and usually relates to network or system conflicts, driver issues, or corrupted files interfering with the proper functioning of Windows or certain applications.
Step-by-Step Guide To Fix Windows Error Code ERROR_106
Step 1: Restart Your Computer
Often the simplest solutions work best.
- Why: Restarting clears temporary files and disconnects stuck processes that might cause error 106.
- How: Click the Start menu > Select Power > Click Restart.
- After reboot, try repeating the action that triggered the error.
Step 2: Run Windows Update Troubleshooter
Since ERROR_106 sometimes happens during updates, using the built-in troubleshooter can automatically fix common issues.
- Open Settings (Windows + I)
- Navigate to Update & Security > Troubleshoot
- Select Additional troubleshooters
- Click Windows Update > Run the troubleshooter
- Follow the on-screen instructions to complete the process.
- Restart your PC and check if the issue persists.
Step 3: Check Network Connection and Reset Network Settings
Network conflicts can trigger ERROR_106. Resetting network adapters often helps.
- Open Command Prompt as Administrator:
- Press Windows key + S, type cmd
- Right-click Command Prompt, select Run as administrator
-
In the terminal, enter the following commands one by one, pressing Enter after each:
netsh winsock reset
netsh int ip reset
ipconfig /release
ipconfig /renew
ipconfig /flushdns - Restart your computer and test the application or update again.
Step 4: Update or Reinstall Problematic Drivers
Drivers, especially for network adapters and system devices, can cause ERROR_106 if outdated or corrupted.
- Press Windows key + X and select Device Manager
- Expand categories like Network adapters, System devices, or the device related to the error.
- Right-click the device and select Update driver > Search automatically for updated driver software
- If no update is found or the problem persists:
- Right-click the device > Uninstall device
- Restart your PC to reinstall the driver automatically.
Step 5: Perform System File Check (SFC) Scan
Corrupted system files often cause unexpected Windows errors.
- Open Command Prompt as Administrator.
-
Type the following and hit Enter:
sfc /scannow
- The scanning process may take 10-15 minutes.
- Once complete, follow any on-screen recommendations.
- Restart your computer.
Step 6: Use DISM Tool to Repair Windows Image
If SFC doesn’t fully resolve the error, the Deployment Image Servicing and Management (DISM) tool may help.
- Open Command Prompt as Administrator.
-
Run these commands one at a time:
DISM /Online /Cleanup-Image /CheckHealth
DISM /Online /Cleanup-Image /ScanHealth
DISM /Online /Cleanup-Image /RestoreHealth - Allow each command to complete, which may take some time.
- Restart your device afterward.
Step 7: Check and Repair Disk Errors
Bad sectors or disk corruption might also contribute to ERROR_106.
- Open Command Prompt as Administrator.
-
Execute:
chkdsk C: /f /r /x
- You’ll be asked if you want to schedule this check the next time the system restarts – type Y and press Enter.
- Restart your computer, and the disk check will run.
Step 8: Temporarily Disable Antivirus and Firewall
Sometimes, third-party antivirus or firewall settings block connections or system operations, triggering ERROR_106.
- Temporarily disable any third-party antivirus software.
- To disable Windows Firewall:
- Open Control Panel > System and Security > Windows Defender Firewall
- Click Turn Windows Defender Firewall on or off on the left panel.
- Select Turn off Windows Defender Firewall (not recommended permanently).
- Test whether the error still occurs.
- If fixing the issue, configure your antivirus/firewall to allow the affected application or update.
Step 9: Perform a Clean Boot
A clean boot starts Windows with minimal drivers and programs to help identify software conflicts.
- Press Windows key + R, type
msconfig, and press Enter. - Go to the Services tab.
- Check Hide all Microsoft services.
- Click Disable all.
- Go to the Startup tab and click Open Task Manager.
- Disable all startup items.
- Close Task Manager and click OK on System Configuration.
- Restart your computer.
- See if ERROR_106 persists—if not, enable services/startup items one at a time to find the culprit.
Step 10: Restore Windows to Earlier Point
If all else fails, restoring your system can undo any harmful changes.
- Press Windows key + S and type Create a restore point.
- Click System Restore and follow prompts to choose a restore point dated before the error appeared.
- Confirm and restore.
Final Tips and Reminders
- Backup your data regularly to avoid losing important files during troubleshooting.
- Always download drivers and updates from official sources.
