In Windows NT 3.x, when your password is 14 days from expiration, youreceive a Password Change Notification when logging on requesting you tochange your password. If the Maximum Password Age is set to 30 days, youreceive the notice when your password is only half way through its lifespan. Although you may wish to change the advance time of the reminder,the Password Change Notification is hard coded at 14 days in Windows NT3.x and is not configurable.
In Windows NT 4.0, a new registry parameter is available to allowadministrators to configure the number of days at which the PasswordChange Notification is presented. The implementation of this new parameterrequires that the registry change be made on the client computer.
WARNING: Using Registry Editor incorrectly can cause serious, system-wideproblems that may require you to reinstall Windows NT to correct them.Microsoft cannot guarantee that any problems resulting from the use ofRegistry Editor can be solved. Use this tool at your own risk.
Run Registry Editor (Regedt32.exe).
From the HKEY_LOCAL_MACHINE subtree, go to the following key:
PasswordExpiryWarning: REG_DWORD: <number of days>
Click OK and quit Registry Editor.
This entry specifies the number of days that a warning message isdisplayed before the user's password expires. This value entry does notnormally appear in the registry unless you add it manually.
In Windows 2000 and later, you can use Group Policy settings to change when the PasswordChange Notification is presented. In Windows 2000, the policy setting is Prompt user to change password before expiration. In Windows 2003, the policy setting is Interactive Logon: Prompt user to change password before expiration.
