Computer Technical Support Companies netsh int ip reset

Since Windows XP does not allow TCP/IP to be uninstalled and reinstalled, the following method from Microsoft is the best method that I have found to reset TCP/IP, once it has been corrupted.

Manual method to reset TCP/IP

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 manually 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.

Warning Programs that access or monitor the Internet such as antivirus, firewall or proxy clients may be negatively affected when you run the netsh winsock reset command. If you have a program that no longer functions correctly after you use this resolution, reinstall the program to restore functionality.

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.

One of the components of the Internet connection on your computer is a built-in set of instructions called TCP/IP. TCP/IP can sometimes become damaged or corrupted. If you cannot connect to the Internet and you have tried all other methods to resolve the problem, TCP/IP might be causing it. Because TCP/IP is a core component of Windows, you cannot remove it. However, you can reset TCP/IP to its original state by using the NetShell utility (netsh). This article describes two ways to reset TCP/IP. You must be logged on to the computer as an administrator. The first method uses a Fix it automated solution to reset TCP/IP. This method is designed for beginning to intermediate users. The second method describes how to use a command to reset TCP/IP manually. This method is designed for advanced users. To have us fix this problem for you, go to the “Fix it for me” section. If you’d rather fix this problem yourself, go to the “Let me fix it myself” section.
