NoteHKLM\SYSTEM\CurrentControlSet\Services\Netlogon\Parameters
| Data type | Range | Default value |
|---|---|---|
| REG_DWORD | 0 | 1- 5 seconds | 2 |
Specifies the minimum amount of time that must separate mailslot messages received by the Net Logon service. If Net Logon receives two mailslot messages within an interval that is less than or equal to the value of this entry, the system considers the messages to be duplicates and ignores the second message.
| Value | Meaning |
|---|---|
| 0 | Net Logon does not ignore mailslot messages, regardless of the interval between messages. |
| 1 - 5 seconds | The time that must elapse between mailslot messages for both to be processed. |
A value of 0 is appropriate when Net Logon must recognize and respond to messages that might appear to be duplicates. For example, when a domain controller is separated from a client computer by a bridge/router, the bridge/router filters outgoing NBF broadcasts but allows incoming broadcasts. Net Logon must respond to the NBF mailslot message which is filtered out by the bridge/router and to the actual, unfiltered mailslot message the system receives.
If the value of this entry is too high, Net Logon might ignore retry attempts from a client.
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.
