How to reinstall TCP/IP in Windows 2000

You might have to reinstall TCP/IP to help resolve some issues, such as improperly configured bindings, dialup clients that are unable to connect to the RAS server, NIC drivers that do not properly bind to the TCP/IP protocol, etc.

To remove TCP/IP in Windows 2000:

  1. Click to clear the TCP/IP check box from all dialup and LAN connections in "Network and Dialup Connections".
  2. Install another protocol (NetBEUI or NWlink) to maintain a placeholder for each conneciton.
  3. Restart your computer
  4. Reinstall TCP/IP, and restart your computer again.

 

How to reinstall TCP/IP in Windows XP
applies both to the Home and Pro editions of XP

In Windows XP, the uninstall button is disabled for the TCP/IP protocol. The TCP/IP stack is considered a core component of the operating system, and it is not possible to uninstall it. Still, in some extreme cases, the most appropriate solution is to reset the TCP/IP stack back to a default state...

There is a NetShell (netsh) command-line scripting utility for the configuring and monitoring of Windows XP networking. Using this tool, a reset command is available that rewrites pertinent TCP/IP registry keys to achieve the same result as the removal and the reinstallation of the protocol. The following registry branches are reset using this tool:

SYSTEM\CurrentControlSet\Services\Tcpip\Parameters\
SYSTEM\CurrentControlSet\Services\DHCP\Parameters\

Comand usage

Simply type the following in Command Prompt:

netsh int ip reset c:\resetlog.txt

"c:\resetlog.txt" being the logfile generated by netsh to store changes being made. If the file exists, the new log will be appended to the end of the existing file.
