How to Reset Inter= net Protocol (TCP/IP) in Windows XP

SUMMARY

Wh= en viewing the list of components for a network interface, you may notice that= the Uninstall butto= n is disabled when Internet Protocol (TCP/IP) is selected. In Windows XP, the TC= P/IP stack is considered a core component of the operating system; therefore, it= is not possible to uninstall TCP/IP in Windows XP.

In extreme cases, reinstalling the Internet Protocol stack may be the most appropriate solution. With the NetShell utility, you can now reset the TCP/= IP stack back to a pristine state, to the same state as when the operating sys= tem was installed.

MORE INFORMATION

The NetShell utility (netsh<= /strong>) is a command-line scripting interface for the configuring and 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 this command is executed, it rewrites pertinent registry keys that are used by t= he Internet Protocol (TCP/IP) stack to achieve the same result as the removal = and the reinstallation of the protocol.

Command Usage<= /o:p>

netsh int ip reset [log_file_name]<= o:p>

To successfully execute the command, you must specify a log file name where actions taken by netsh will be recorded. For example, typing either of the examples that are liste= d in the "Command Samples" section later in this article at a command = prompt would reset the TCP/IP stack on a system and record the actions that were t= aken 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 w= here the log will be created. In either case, where the specified log file alrea= dy 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 comman= d is issued. The actual log file may vary depending on the configuration of the system on which the command is issued. In some cases, there may be no actio= ns logged in the file, which typically is the case when the TCP/IP registry ke= ys have not been altered from their original configuration. =
