INTRODUCTION
In Microsoft Windows XP, the TCP/IP stack is considered a core component of the operating system, and you cannot remove TCP/IP. Therefore, when you view the list of components for a network interface, you may notice that the Uninstall button is disabled when Internet Protocol (TCP/IP) is selected. In extreme cases, the best solution for this issue may be to reinstall the Internet Protocol stack. But with the NetShell utility, you can reset the TCP/IP stack to restore it to its state that existed when the operating system was installed. This article describes how to use the NetShell utility for this purpose.
MORE INFORMATION
The NetShell utility (netsh) is a command-line scripting interface for configuring and monitoring Windows XP networking. This tool provides an interactive network shell interface to the user.

In Windows XP, a reset command is available in the IP context of the NetShell utility. When you run the reset command, it rewrites pertinent registry keys that are used by the Internet Protocol (TCP/IP) stack to reach the same result as the removal and the reinstallation of the protocol.

Command usage
netsh int ip reset [log_file_name]
To run the command successfully, you must specify a file name for the log where actions that are taken by netsh will be recorded. For example, at a command prompt, type either of the samples that are listed in the "Command samples" section. The TCP/IP stack will then be reset on a system, and the actions that were taken will be recorded in the log file, Resetlog.txt. The first sample creates the log file in the current directory, while the second sample creates a path where the log will reside. In either case, where the specified log file already exists, the new log will be appended to the end of the existing file.


Command samples
netsh int ip reset resetlog.txt
netsh int ip reset c:\resetlog.txt
Sample Log File for NETSH INT IP RESET
The following is a sample of the log file that is generated by netsh when an IP reset command is issued. The actual log file may vary depending on the configuration of the system where the command is issued. When the TCP/IP registry keys have not been altered from their original configuration, there may be no actions logged in the file.
