Hey Experts,

I'm having an odd issue. A coworker installed sharepoint on an IIS server and I'm not sure what else was done, but now no users can authenticate via ANY IIS server when the User Must Change Password at next Logon is selected. Otherwise it authenticates fine. I thought it might have been because he wiped out the IISADMPWD feature on that one partifuclar server, but no IIS server allows me to authenticate/change password anymore. please advise!

This behaviour is by design.  Once a password expires, access to all domain resources is chopped.

The user would have to logon to the domain first, and set their new password in order to access the sharepoint server.

Once they've done this, there should be no authentication prompt.
If a user is working remotely,....you can set the password for them, and they can continue normally.

Understood, but it has always prompted for a password-change up until recently right within the browser using IISADMPWD.

thanks. I just discovered that Firefox gets the change password screens, but IE does not and fails to authenticate. Any ideas what would cause this now?

Try putting it in the trusted sites zone,...or allowing popups for the sharepoint site.

OK that allowed me to the change password screen in IE. I've now narrowed it down to the wildcard application maps (JRUN) that do not forward you to the password change screen. ???

Since the wildcard mappings for CGI apps are working without issue in Firefox, it's implied to me that this is probably some security setting in IE.  I would think if it were a configuration error on the server that it wouldn't work at all.

agree ?

So at least we have it popping up now....  but the obvious question remains...  what has changed ?
Any windows updates that were recently applied ? Group policy changes ?

Just as a test...temporarily lower your security level on the trusted sites zone.  Set it all the way to low and give it a try.

401.2 Denied by Server Configuration
This error indicates that the web server is configured to require certain authentication protocols for communication, but the browser failed to use any of those authentication protocols. The corrective action should be to either configure to require an authentication protocol acceptable to the client, or use a client that satisfies the server authentication protocol requirements.

Obviously a browser issue.
