ExpectedDialupDelay

HKLM\SYSTEM\CurrentControlSet\Services\Netlogon\Parameters

Description

Specifies an amount of additional time that the Net Logon service waits for a response from a domain controller. If the domain controller does not respond before the total time allowed elapses, Net Logon assumes that the domain controller is not available and proceeds accordingly.

This entry is designed to allow extra time for a response when the domain controller is connected by a slow dialup link.

This entry is used to extend time limits for the following conditions:

• When locating a domain controller in a trusted domain, such as when authenticating a user's logon credentials.

• Net Logon allows fifteen seconds, plus the value of ExpectedDialupDelay for the domain controller to respond. The timer begins when the first of three datagrams is sent to the domain controller.

  Timeout = 15 seconds + ExpectedDialupDelay seconds
• When an API call is issued over a secure channel to a domain controller that has already been located.

• Net Logon allows 45 seconds, plus the value of ExpectedDialupDelay for the domain controller to respond.

  Timeout = 45 seconds + ExpectedDialupDelay seconds

To give remote domain controllers more time to respond, you can add this entry to the registry and increase its value.

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.
