reinstall the TCP/IP protocol in Windows XP?
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 <PATH>\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 <PATH>\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 =
