JSI Tip 4785. How do I reinstall the TCP/IP protocol in Windows XP?

If you need to reinstall the TCP/IP protocol in Windows XP, you will notice that theUninstall 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_MACHINESYSTEMCurrentControlSetServicesTcpipParametersHKEY_LOCAL_MACHINESYSTEMCurrentControlSetServicesDHCPParameters

NOTE: If resetlog.txt exists, it will be appended.

Here is a sample snippet of a log file:
