Situation: After a new windows update, I can’t access any websites. However, I can ping them such as google.com and yahoo.com. I just can’t access them with page can’t be displayed message.
Troubleshooting: 1. If you have any anti virus or security software, disable it for a test.
2. Reinstall Drivers.
3. ipconfig /release /renew.
4. Change the DNS server, for example use 8.8.8.8.
5. Flush DNS by running these commands: ipconfig /flushdns and ipconfig /registerdns.
6. Run netsh winsock reset command.
7. Make sure no proxies set -> all default obtain automatically.
8. Make sure it is multihomed computer or the computer with multiple Network connections..
in our case, after disabling Symantec Endpoint Protection auto protection, I can access the websites. Then enable SEP.
Try reinitialising the network states. Run the following commands in an elevated cmd shell:
Reset WINSOCK entries to installation defaults:
netsh winsock reset catalog
Reset TCP/IP stack to installation defaults:
netsh int ip reset reset.log
Reset Firewall to installation defaults:
netsh advfirewall reset
Flush DNS resolver cache:
ipconfig /flushdns
Renew DNS client registration and refresh DHCP leases:
ipconfig /registerdns
Flush routing table (reboot required):
route /f
