    What netsh winsock reset command does are it resets Winsock Catalog to a clean state or default configuration.

So all previously-installed LSPs must be reinstalled. This command does not affect Winsock Name Space Provider entries.

Reinstall and Reset TCP/IP (Internet Protocol) in Windows Vista, 2003 and XP

reinstall and reset the TCP/IP stack (Internet Protocol) to its original state as same as when the operating system was installed in Windows XP and Windows 2003, simply use the following command in command prompt shell. A log file name must be specified where actions taken by netsh will be recorded on newly created or appended if already existed file..

netsh int ip reset [ log_file_name ]

netsh int ip reset resetlog.txt

For Windows Vista, things work a little different due to introduction of UAC (Guide: Disable UAC). Use this guide to perform a reinstalling of TCP/IP protocol in Vista:

  1. Click on Start button.
  2. Type Cmd in the Start Search text box.
  3. Press Ctrl-Shift-Enter keyboard shortcut to run 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.

The command will remove all user configured settings on TCP/IP stack and return it to original default state by rewriting pertinent registry keys that are used by the Internet Protocol (TCP/IP) stack to achieve the same result as the removal and the reinstallation of the protocol. The registry keys affected are:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters\

and

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\DHCP\Parameters\
