IE Authentication Prompt, Pass-through authentication stops working

We use Business Portal 2.0 (built on Sharepoint 2.0) for our intranet.  We use pass-through authentication for the intranet.  

Through AD (2003) we enforce a 90-day password expiration policy.

On random machines (WinXP, IE7), when they have to reset their password, IE fails to register the change and the authentication prompt begins to pop-up every time they try to go to the intranet.  They can manually enter the credentials every time and it works, but we want the pass through authentication to work.

This does not seem to happen consistently across the network (e.g. not all IE7 users have this issue as far as we can assess).  

Our really lame workaround has been to uninstall IE and reinstall and that mostly works.  However, I have a machine on hand for which this is not resolving the issue.  

Can anyone give me pointers on where I can look to see if I can flush out the old password...Clearing the cache, cookies, temp internet files, etc., does not cut it?  

Thanks in advance for any feedback.

On of the items we have found is that when a user is prompted, they click the "Save Password". On subsequent attempts to access the site, the saved password is used instead of the trying to re-authenticate against the network. Most users do not notice until they change their password, at which time the saved password is now incorrect. To remove the saved password, Go to the "User Accounts" control panel, switch to the Advanced Tab (it appears that you need administrator permissions to see this tab) and click the Manage Passwords button. From there, just remove any stored passwords listed for your site(s).

If you do not see the Advanced tab mentioned above, try the following from the Run dialog box:
rundll32.exe keymgr.dll,KRShowKeyMgr

Thank you very much.  Pretty obvious, but just couldn't make my brain look in that direction...wanted it to be something in IE.  You solved the issue right away, thank you very much.
