The option to remove and reinstall TCP/IP is greyed out. Logged in as Admin, I cannot change this. How is TCP/IP reinstalled without having to wipe and start over?

If you need to reinstall the TCP/IP protocol in Windows XP, you will notice that the Uninstall button is disabled.

The TCP/IP stack is a core component of Windows XP and can NOT be uninstalled.

You can reset the stack to its' installed state by using the built-in netsh tool.

When you run:
netsh int ip reset \resetlog.txt

the following registry keys are rewritten:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters\
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\DHCP\Parameters\
NOTE: If \resetlog.txt exists, it will be appended.
Here is a sample snippet of a log file:

reset SYSTEM\CurrentControlSet\Services\Dhcp\Parameters\Options\15\RegLocation
old REG_MULTI_SZ =
SYSTEM\CurrentControlSet\Services\Tcpip\Parameters\Interfaces\?\DhcpDomain SYSTEM\CurrentControlSet\Services\TcpIp\Parameters\DhcpDomain

NOTE: If the log file is empty, the registry keys have not been altered.
