As a network engineer with over 10 years of experience, I often come across the frustrating “Ping: General Failure” error when testing network connectivity issues for clients. This error essentially means that the ping test has failed and the network is unable to communicate between devices.
Troubleshooting this error can be tricky because there are a number of potential causes. However, with the right approach and tools, the issue can usually be resolved. In this comprehensive guide, I’ll walk through the common causes and solutions for troubleshooting the “Ping: General Failure” error on both Windows and Linux systems.

Common Causes of the “Ping: General Failure” Error
Before jumping into solutions, it’s important to understand what typically causes this error so you can target your troubleshooting:
- Firewall or security software blocking ping requests: Many firewalls and security tools will block ICMP ping requests by default as a security measure. This will lead to failed pings.
- Network misconfiguration: Incorrect TCP/IP, DNS, proxy, or VPN settings can prevent connectivity between devices leading to failed pings.
- Faulty network driver or hardware: Damaged network cables, NICs, switches, etc. can cause connectivity issues.
- IPv6 connectivity problems: If IPv6 is misconfigured but IPv4 is working, you may see failures when pinging IPv6 addresses.
Troubleshooting Steps and Potential Solutions
With the common causes in mind, here are the key things I try when troubleshooting “Ping: General Failure” errors:
1. Check Security and Firewall Settings
Temporarily disable any firewalls, anti-virus, VPN clients, etc. and try to ping again. If pings now work, modify firewall rules to allow ICMP traffic.
2. Verify Network Configuration
Check IP addressing, DNS, proxies, VLANs, etc. and correct any invalid settings. Flush DNS and renew IP addressing.
3. Reset Networking Components
Reset the TCP/IP stack with netsh int ip reset. Restart networking services and devices. Reinstall drivers if needed.
4. Standard Network Troubleshooting
Use tracert, pathping, nmap port scans and other tools to isolate the failure point. Check cables, switches, NICs, etc.
5. Disable IPv6 Temporarily
Disable IPv6 adapters and transition technologies if only IPv6 connectivity is failing.
6. Contact ISP if Problem Persists
For persistent problems, contact your ISP or network provider to troubleshoot further.
Best Practices to Avoid “Ping: General Failure”
While troubleshooting steps can resolve the error after it occurs, avoiding “Ping: General Failure” in the first place should be the goal. Here are some best practices:
Keep Software Updated
Regularly update network drivers, firmware, operating systems, and applications to prevent bugs from causing connectivity issues.
Properly Configure Firewalls
Configure firewall software to allow ICMP traffic to prevent failure during routine ping tests.
Validate Network Changes
Any time infrastructure or configurations are changed, validate connectivity with ping tests to avoid introducing issues.
Monitor Critical Infrastructure
Use network monitoring to track the status of critical networking components in real-time. This allows problems to be identified rapidly.
Document the Network
Keep detailed documentation on network designs, addressing schemes, VLANs, etc. to more easily troubleshoot when issues occur.
When to Seek Additional Help
While the troubleshooting steps and best practices above can resolve most instances of “Ping: General Failure” errors, more complex networking issues can sometimes be the root cause. If you have exhausted the typical troubleshooting methodology without resolving the issue, it may be time to open a case with your infrastructure vendor or managed service provider. Their engineers will have additional tools and methods to identify and correct stubborn network problems leading to failed pings.
Conclusion
Getting the frustrating “Ping: General Failure” message can be disruptive but armed with the troubleshooting techniques outlined in this guide, the issue can usually be corrected in a reasonable time frame. Key things to try include reviewing firewall settings, validating configurations, resetting networking components, standard connectivity troubleshooting, and disabling IPv6. And if the problem persists after exhausting your efforts, don’t hesitate to engage professional help. By combining troubleshooting best practices with monitoring and preventative maintenance, instances of failed ping tests can be minimized keeping the network humming along.
