|---|---|---|
| REG_DWORD | 0x0 - 0xFFFFFFFF seconds | 0x1E (30 seconds) |
Determines for how long the DNS client on Windows 2000 Professional stops sending queries when it suspects that the network is down.
When the DNS client does not receive responses to repeated queries sent to any network adapter, the DNS client stops sending queries for the time specified in the value of this entry. During that time, the DNS client returns a timeout response to all queries.
If the value of this entry is 0x0, this optimizing feature is disabled. DNS continues to send queries to an unresponsive network.
To make changes to this entry effective, restart the DNS client service or restart Windows 2000.
Note
This entry is used only on Windows 2000 Professional.
