Before you edit the registry, make sure you understand how to restore it if
a problem occurs. For information on how to do this, view the "Restoring
the Registry" online Help topic in Regedit.exe or the "Restoring a Registry
Key" online Help topic in Regedt32.exe.

SUMMARY
=======

A Windows NT RAS client can instruct a Windows NT RAS server how long to wait
before calling back, if the Callback feature is enabled. The default for
callbacks is 12 seconds. This article describes how to alter this setting.

MORE INFORMATION
================

WARNING: Using Registry Editor incorrectly can cause serious problems that may
require you to reinstall your operating system. Microsoft cannot guarantee that
problems resulting from the incorrect use of Registry Editor can be solved. Use
Registry Editor at your own risk.

For information about how to edit the registry, view the "Changing Keys And
Values" online Help topic in Registry Editor (Regedit.exe) or the "Add and
Delete Information in the Registry" and "Edit Registry Data" online Help topics
in Regedt32.exe. Note that you should back up the registry before you edit it.

To change the default callback time, add a new REG_DWORD value named
DefaultCallbackDelay to the following registry key:

  HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\RasMan\PPP

Set the value of the DefaultCallbackDelay value from 0 to 255. This is the
callback delay time in seconds.
