MS has a knowledgebase article on resetting TCP/IP

How to reset Internet Protocol (TCP/IP) in Windows XP 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.
