Reinstalling TCP/IP Network Stack Windows 7

Taken from [https://pandapow.co/how-to/win-reset-adapter/] – These instructions were used by a colleague recently when his network stack was b0rK3n. Running both the reset for tcp4 and tcp6 seemed to be key. Just resetting 4 did not resolve his issue.

    Mike:

    Yesterday, I screwed-up my TCP/IP stack (on Windoze/7) something
    ugly. My own damned fault.

    I tried dozens of “fixit”s but none of them worked until I found
    yours. This e-mail proves your solution worked.

    Thank you very much or being such a good “netizen”.
