Reinstall and reset TCP/IP (Internet protocol)

  1. Click on the Start button.
  2. Type Cmd in the Start Search text box.
  3. Press Ctrl + Shift + Enter keyboard shortcut to run a command prompt as administrator. Allow elevation request.
  4. Type netsh int ip reset in the command prompt shell, and then press the Enter key.
  5. Restart the computer.

Note: if you're using manually assigned TCP/IP settings, take notes as this will reset to the default 'automatically obtained'.

whats the difference between doing this, and using "add new hardware" then select "windows tcp ip protocol driver" ? this work fo XP, in win7 there's no such option ... – None – 2009-08-28T02:23:12.497

are you looking for TCPIP.SYS? please tell us exactly what you want to achieve. – None – 2009-08-28T02:53:19.453

funny, only this afternoon one of my windows 7 VMs crashed due to a corrupt driver (tcpip.sys), as suggested, a repair installation solved the issue. – None – 2009-09-11T22:50:07.353

it seems there is no other way... – None – 2009-09-12T14:46:10.300

I have used this a thousand times. How to reset TCP/IP by using the NetShell utility provides an EXE file to automatically do that reset for you.
