We have developped an Visual FoxPro Internet Web application where each user will be using the Windows NT authentification from the browser to access the Web site. I mean that the account table in the Windows NT will be used from the browser to access the Web site which is driven from IIS.

We need to force each account password to expire after 21 days. In normal situation, when a user is logging in to a Windows NT server from a workstation, if the password expires, he will be prompt to update his password with the password dialog. However, from the Web, this is not possible.

Is there any 3rd party, plug-ins, or whatever the technology is to be able to accomplish that from the Web? Our last solution is to force an HTML login and process everything from Visual FoxPro with NETAPI32 to give the user a form to update his Windows NT password.
