INTRODUCTION
In Microsoft Windows XP, the TCP/IP stack is considered a core component of the operating system, and you cannot to remove TCP/IP. Therefore, when you view the list of components for a network interface, you may notice that when Internet Protocol (TCP/IP) is selected, the Uninstall button is disabled. In extreme cases, the most appropriate solution may be to reinstall the Internet Protocol stack. With the NetShell utility, you can reset the TCP/IP stack to restore it to a pristine state (the same 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 the configuring and the monitoring of 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. SYSTEM\CurrentControlSet\Services\Tcpip\Parameters\
SYSTEM\CurrentControlSet\Services\DHCP\Parameters\
Command usage
netsh int ip reset [log_file_name]
To run the command successfully, you must specify a log file name where actions taken by netsh will be recorded. For example, type either of the examples that are listed in the "Command samples" section at a command prompt to reset the TCP/IP stack on a system and to record the actions that were taken in the log file, Resetlog.txt. The first sample creates the log file in the current directory, while the second sample demonstrates the use of a path where the log will be created. 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
