Cached Credentials Problems

By longgreenpike58 ·
We have a sales force with laptops. They log into our domain once or
twice a month, then spend the rest of their time on the road.

We have started to expire passwords, but are running into cache
credential issues. For example, John Doe logs into the LAN with password of
december22. His password expires while he is out of the office.
When he attempts to log into OWA 2003, he is prompted for a new password.
He changes his password to december33 and successful accesses OWA.
However, the next time he attempts to log into his laptop with december33,
he gets invalid password, because cached credentials are looking for

Any suggestions?

You could use a GPO for these users to increase the time period for their cached credentials.

Or you could set up a terminal server with web access to allow the users to change their passwords.

MS has identified this as a problem. See this MS article for explanation and fix:

We had a very similar problem. We had the ability to force them to change their passwords via dial-up networking (Check box from the login screen) rather than through OWA.

It is a short term fix, as SP2 seems to have corrected this problem...

I had that problem last week. My co domain password expired when I was in China. When I wanted to send/receive email using Outlook, it wont let me. So I tried to do that using OWA, it prompted me to change password. I changed the password and could send/receive my emails using OWA. Next, I VPN into my office domain and change my password using CTRL+ALT+DEL/change password to the new password. I was able to change my domain password on my laptop to the new password.

Delete Cookies, and Index.dat

by redwraith94 In reply to Cached Credentials Proble ...

Microsoft recommends to delete cookies from the browser, 'usually' by closing the browser. However that doesn't work.

You must delete the cookies, and 2 copies of Index.dat

After deleting cookies navigate to:

C:\Documents and


C:\Documents and Settings\%username%\Userdata\Index.dat

Make sure all instances of Internet explorer are closed.

and delete both index.dat files. These are recreated the next time the browser is opened.

So, for a user named 'me', it would be:

C:\Documents and Settings\ME\Cookies\Index.dat


C:\Documents and Settings\ME\Userdata\Index.dat

If this process gives any errors, then make sure that all instances of the 'iexplore.exe' process are closed.

Task Manager > Processes 'Tab'
