Description

Specifies the 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, then Net Logon assumes that the domain controller is not available, and it proceeds accordingly.

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

This entry extends 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 15 seconds plus the value of this entry for the domain controller to respond. The time begins when the first of three datagrams is sent to the domain controller.

    Timeout = 15 seconds + ExpectedDialupDelay seconds

  • When an application programming interface (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 this entry 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.

This entry does not exist in the registry by default. You can add it by using the registry editor Regedit.exe.
