NoteHKLM\SYSTEM\CurrentControlSet\Services\NdisWan\Parameters
| Data type | Range | Default value |
|---|---|---|
| REG_DWORD | 0 | 1 | 1 |
Determines whether NdisWan drivers consider Internet Group Management Protocol (IGMP) packets to be valid communications traffic.
Many servers send IGMP packets periodically to prevent a quiet, but active line from being mistaken for an idle line. These packets can be misinterpreted as communication. They can also prevent a truly idle line from being disconnected.
| Value | Meaning |
|---|---|
| 0 | IGMP packets are considered to be valid communications traffic that keeps a line active. |
| 1 | IGMP packets are filtered out and not counted as valid communications traffic. |
Note
Windows 2000 does not add this entry to the registry. You can add it by editing the registry or by using a program that edits the registry.
