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:

reset   SYSTEMCurrentControlSetServicesDhcpParametersOptions15RegLocation            old REG_MULTI_SZ =                SYSTEMCurrentControlSetServicesTcpipParametersInterfaces?DhcpDomain                SYSTEMCurrentControlSetServicesTcpIpParametersDhcpDomainadded   SYSTEMCurrentControlSetServicesNetbtParametersInterfacesTcpip_{2DDD011E-B1B6-4886-87AC-B4E72693D10C}NetbiosOptionsadded   SYSTEMCurrentControlSetServicesNetbtParametersInterfacesTcpip_{BAA9D128-54BB-43F6-8922-313D537BE03E}NetbiosOptionsreset   SYSTEMCurrentControlSetServicesNetbtParametersInterfacesTcpip_{BD2859BA-B26A-4E2B-A3FE-3D246F90A81A}NameServerList            old REG_MULTI_SZ = 10.1.1.2deleted SYSTEMCurrentControlSetServicesNetbtParametersEnableLmhostsadded   SYSTEMCurrentControlSetServicesTcpipParametersInterfaces\{2DDD011E-B1B6-4886-87AC-B4E72693D10C}AddressTypeadded   SYSTEMCurrentControlSetServicesTcpipParametersInterfaces\{2DDD011E-B1B6-4886-87AC-B4E72693D10C}DefaultGatewayMetricadded   SYSTEMCurrentControlSetServicesTcpipParametersInterfaces\{2DDD011E-B1B6-4886-87AC-B4E72693D10C}DisableDynamicUpdatedeleted SYSTEMCurrentControlSetServicesTcpipParametersInterfaces\{2DDD011E-B1B6-4886-87AC-B4E72693D10C}DontAddDefaultGatewayreset   SYSTEMCurrentControlSetServicesTcpipParametersInterfaces\{2DDD011E-B1B6-4886-87AC-B4E72693D10C}EnableDhcp            old REG_DWORD = 0

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