Troubleshooting NordVPN Connection Error 720 on Windows 11 After Network Adapter Reset (TAP Driver Fix)

Troubleshooting NordVPN Connection Error 720 on Windows 11 After Network Adapter Reset (TAP Driver Fix)

As a Senior Technical Support Engineer and PC Security Specialist, I frequently encounter VPN connection issues stemming from underlying network misconfigurations. NordVPN Connection Error 720 on Windows 11, particularly after a network adapter reset, is a common frustration that points directly to problems with the VPN's virtual network interface – specifically the TAP-Windows Adapter V9 driver. This comprehensive guide will walk you through the diagnostic steps and provide actionable solutions to restore your secure VPN connection.

Symptom Analysis & Why This Error/Issue Occurs

When attempting to connect to NordVPN, users encounter "Error 720: A connection to the remote computer could not be established. You might need to adjust the network settings for this connection." This error is often accompanied by an inability to access the internet through the VPN, even if the underlying internet connection is stable. The critical detail here is its occurrence after a network adapter reset, which includes actions like "Network Reset" in Windows Settings, manual driver reinstallation, or even certain Windows updates.

The root cause of Error 720 in this context is typically a corrupted, missing, or improperly configured NordVPN TAP driver. A network reset often involves reinitializing the entire network stack, which can inadvertently uninstall or disable crucial virtual network adapters and their associated drivers. Without a correctly functioning TAP-Windows Adapter V9, NordVPN cannot establish the virtual tunnel necessary for a secure connection, leading to the 720 error.

Pre-requisites & Safety Backups (Warning before tweaking system)

Before proceeding with any system-level changes, it is paramount to ensure system stability and data integrity. While the following steps are generally safe, proper preparation mitigates potential risks.

  • Administrative Privileges: You must be logged into Windows 11 with an administrator account to perform these troubleshooting steps.
  • Stable Internet Connection: Ensure your regular internet connection is working correctly before attempting VPN connection.
  • Create a System Restore Point: This allows you to revert your system to a previous working state if any issues arise.

To create a restore point:


1. Press Win + R, type sysdm.cpl and press Enter.
2. Go to the System Protection tab.
3. Click Create...
4. Give your restore point a descriptive name (e.g., "Before NordVPN Fix") and click Create.

For critical data, consider using reliable best data recovery software to perform a full system backup, ensuring that your valuable information remains secure regardless of any unforeseen system changes during the troubleshooting process.

Step-by-Step Actionable Solutions

Solution 1: Reinstall the NordVPN TAP Adapter Driver

This is the most common fix for Error 720 after a network reset, as it directly addresses potential corruption or absence of the TAP driver.

  1. Uninstall Existing TAP Drivers:
    • Press Win + X and select Device Manager.
    • Expand Network adapters.
    • Look for any entry named TAP-Windows Adapter V9 or similar (e.g., NordVPN TAP Adapter).
    • Right-click on it and select Uninstall device. Check the box Attempt to remove the driver for this device if available.
    • Repeat for any other TAP adapters.
  2. Reinstall NordVPN:
    • Close NordVPN application.
    • Go to Settings > Apps > Installed apps.
    • Find NordVPN, click the three dots, and select Uninstall.
    • Reboot your PC.
    • Download the latest version of NordVPN from the official website and install it. This will automatically reinstall the necessary TAP driver.
    • After installation, try connecting to NordVPN.

Solution 2: Reset Network Configuration via Command Prompt

A corrupted network stack can prevent VPNs from functioning. Resetting it can resolve underlying communication issues.

  1. Open Command Prompt as an administrator: Search for CMD, right-click and select Run as administrator.
  2. Execute the following commands one by one, pressing Enter after each:

netsh winsock reset
netsh int ip reset
ipconfig /release
ipconfig /renew
ipconfig /flushdns

After running all commands, restart your computer and attempt to connect to NordVPN.

Solution 3: Verify and Adjust TAP Adapter Settings

Sometimes, even if the driver is installed, its network settings might be misconfigured.

  1. Press Win + R, type ncpa.cpl, and press Enter to open Network Connections.
  2. Locate the NordVPN TAP Adapter (it might be named "Ethernet" with a description like "TAP-Windows Adapter V9" or "NordVPN TAP Adapter").
  3. Right-click on it and select Properties.
  4. In the Networking tab, ensure that Internet Protocol Version 4 (TCP/IPv4) is checked.
  5. Select Internet Protocol Version 4 (TCP/IPv4) and click Properties.
  6. Ensure that Obtain an IP address automatically and Obtain DNS server address automatically are selected. Click OK.
  7. Optionally, try disabling Internet Protocol Version 6 (TCP/IPv6) by unchecking its box if you continue to face issues, as IPv6 can sometimes cause conflicts with VPNs.
  8. Click OK to close the properties window.
  9. Restart your PC and try connecting to NordVPN.

Recommended Software & Tools

Maintaining a healthy and secure PC environment goes beyond just fixing VPN errors. Incorporating robust software tools is essential for optimal performance and protection.

  • Secure VPN Service: Beyond troubleshooting, leveraging a top-tier secure VPN service like NordVPN is critical for online privacy and security. Its robust encryption, extensive server network, and advanced features ensure your digital footprint is protected from cyber threats and surveillance.
  • Enterprise Antivirus Protection: Complement your VPN with leading enterprise antivirus protection. Solutions like Bitdefender, Kaspersky Business Security, or Sophos Endpoint provide comprehensive defense against malware, ransomware, and phishing attacks, crucial for both personal and professional data integrity.
  • Best Data Recovery Software: In unexpected data loss scenarios, having access to the best data recovery software (e.g., EaseUS Data Recovery Wizard, Stellar Data Recovery) can be a lifesaver. It’s a vital safety net for accidental deletions, drive formatting, or system crashes.
  • PC Performance Optimization Tools: To keep your Windows 11 system running smoothly, utilize PC performance optimization tools. Built-in Windows tools like Disk Cleanup and Storage Sense, alongside third-party utilities, can help declutter your system, manage startup programs, and ensure efficient operation, preventing slowdowns that can affect network connectivity.

Frequently Asked Questions

Q1: Why does Error 720 only appear after a network reset?
A1: A network reset in Windows reinitializes the entire network stack and its associated drivers. This process can inadvertently corrupt, misconfigure, or even remove the specialized virtual network adapter (TAP driver) that NordVPN relies on. When the system comes back up, the VPN client cannot find or properly utilize this adapter, leading to Error 720.

Q2: Is NordVPN considered a secure VPN service for Windows 11?
A2: Yes, NordVPN is widely regarded as a highly secure VPN service. It employs strong encryption protocols (OpenVPN, NordLynx), adheres to a strict no-logs policy, and includes features like a kill switch, DNS leak protection, and Threat Protection (malware blocking). Its performance and security make it an excellent choice for protecting your online activities on Windows 11.

Q3: What if reinstalling NordVPN doesn't fix the TAP driver issue?
A3: If a clean reinstallation of NordVPN doesn't resolve the issue, it suggests a deeper underlying network stack corruption or a persistent driver conflict. In such cases, ensure you've tried all the `netsh` commands (Solution 2) and consider using the Windows "Network Reset" feature (Settings > Network & internet > Advanced network settings > Network reset), followed by a clean NordVPN install. If problems persist, contacting NordVPN support or performing a Windows in-place upgrade (repair install) might be necessary as a last resort, after ensuring your data is backed up with best data recovery software.
