Question

Difficulty: HardMicrosoft Command-Line Tools

A desktop support technician is troubleshooting a Windows 11 workstation experiencing persistent network stack corruption and invalid socket bindings that prevent all web traffic. Standard GUI troubleshooter fixes have failed. The technician opens an administrative Command Prompt to perform a complete CLI-based network stack reset and system reboot. Place the command execution steps in the correct operational sequence to resolve the issue.

  1. 1Flush the local DNS resolver cache to clear corrupted hostname mappings using ipconfig /flushdns.
  2. 2Reset the Windows Sockets API catalog to its default clean configuration using netsh winsock reset.
  3. 3Re-initialize the TCP/IP protocol stack and rewrite its registry keys using netsh int ip reset.
  4. 4Force an immediate system restart to re-initialize kernel network drivers and commit protocol changes using shutdown /r /t 0.

Answer

The correct operational sequence begins with flushing the DNS resolver cache (ipconfig /flushdns), followed by resetting the Winsock API catalog (netsh winsock reset), then resetting the TCP/IP protocol stack registry state (netsh int ip reset), and finally performing an immediate system restart (shutdown /r /t 0).
Resolving severe CLI network transport failures requires systematically clearing stored DNS records, resetting corrupt socket API layers via netsh winsock reset, restoring TCP/IP protocol registry keys via netsh int ip reset, and finally executing shutdown /r /t 0 to reload system kernel drivers.

Step-by-Step Solution

1
Execute ipconfig /flushdns in elevated Command Prompt.
Purges all local DNS cache entries from memory.
Clears invalid address resolutions before altering underlying protocol layers.
2
Execute netsh winsock reset.
Restores the Windows Sockets catalog to default operational state.
Fixes socket binding errors and removes corrupted network interface hooks.
3
Execute netsh int ip reset.
Overwrites IPv4 and IPv6 registry parameters with default values.
Ensures core TCP/IP stack configuration parameters are completely restored.
4
Execute shutdown /r /t 0.
Reboots the operating system immediately without delay.
Commits Winsock and TCP/IP kernel driver modifications upon system initialization.
