HKLM\SYSTEM\CurrentControlSet\Services\Tcpip\
The Tcpip\Performance subkey contains entries for the performance counter dynamic-link library (DLL) for the TCP/IP service. These values are used by the performance library to collect data for the performance counters that monitor the service. These entries are maintained by the system and should not be changed.
To make changes to entries in this subkey effective, restart the Remote Registry Service or restart Windows 2000.
Tip
Most entries that can appear in this subkey are described in the generic Performance subkey. The entries described here are specific to the Tcpip\Parameters subkey and have no effect unless they appear in this subkey.
