Error 628 is a common issue that occurs in Windows environments when a connection attempt to a network or the internet is prematurely terminated. This error is typically associated with VPN connections or dial-up networking. It can be caused by several factors, including incorrect network settings, outdated drivers, or issues with the network provider. This article will guide you through the steps to troubleshoot and resolve Error 628 in Windows.

Examples:

1. Check Network Configuration:

   • Ensure that your network settings are correctly configured. Incorrect settings can lead to Error 628.
   • Open the "Network and Sharing Center" and verify your connection settings.

2. Update Network Drivers:

   • Outdated network drivers can cause connectivity issues. Update your drivers to the latest version.
   • To update drivers:
     • Press Windows + X and select "Device Manager."
     • Expand "Network adapters," right-click your network device, and choose "Update driver."

3. Disable Firewall Temporarily:

   • Sometimes, the firewall may block the connection. Temporarily disable it to check if it's causing the issue.
   • Open "Control Panel" > "System and Security" > "Windows Defender Firewall" > "Turn Windows Defender Firewall on or off."

4. Use Command Prompt to Reset TCP/IP:

   • Resetting TCP/IP can resolve network issues.
   • Open Command Prompt as an administrator and execute the following commands:

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

   • Restart your computer after executing these commands.

5. Check VPN or Dial-up Settings:

   • If using a VPN or dial-up connection, ensure that the settings are correct.
   • Verify the server address, username, and password.

6. Contact ISP or Network Administrator:

   • If the problem persists, contact your Internet Service Provider (ISP) or network administrator for further assistance.
