How to repair and reset the Windows TCP/IP stack ?

The TCP/IP stack Winsock settings in Windows can sometimes get corrupted, causing various problems with internet connectivity. Such corruption can be caused by various networking software installations, or virus/malware infections.

Corrupt Winsock can cause various networking errors, including inability to surf the internet with "Page cannot be displayed" browser error, even though the network card appears to be connected. Sometimes the ICS service is terminated as well.

To reset the Windows Vista/7/8/10 TCP/IP stack:

1. Run Elevated Command Prompt:
- Click the Start button
- Type: cmd in the Start Search text box.
- right-click and choose "Run as Administrator" (alternatively, press CTRL-SHIFT-ENTER to run it as administrator), and allow elevation request
2. Type: netsh winsock reset in the shell and hit Enter
3. Type: netsh int ip reset and hit Enter again.
4. Restart the computer

Alternatively, if you use the TCP Optimizer, just click the "Reset Winsock" and/or "Reset TCP/IP" in its "File" menu, then reboot.

reset the stack and it's all good, my dell service agreement wanted to charge me to send somebody round to reset it for me! At least they told me that the tcp/ip stack needed resetting and I just googled it...

Cheers everybody

I went to Microsoft and they were no help because they wouldn't tell me what I needed to do to accomplish the elevate command. I followed your instructions and I am back running the way I should be. Thank you so much. This problem occurred because of a malicious program called Scorpion Saver. It has been troubling my computer for weeks. Hopefully this is the last place it was embedded.
