When the Archive Manager (AM) website is configured for Integrated Authentication with Automatic Logon in the Intranet Zone, Internet Explorer (IE) is supplying the wrong credentials. Other web browsers are not affected and continue to work correctly.
Confirmation of the incorrect credentials being used can be found in the IIS logs on the AM webserver.
IE is using cached credentials for the AM website and sending the wrong username and/or password combination.
On the client machine with the incorrect cached credentials make a backup of the files found in the following locations then clear the cached credentials by removing the files from these locations:
For Windows Vista, 7, 2008 and newer:
For Windows XP/2003 and older:
C:\Documents and Settings\USERNAME\Application Data\Microsoft\Credentials
C:\Documents and Settings\USERNAME\Local Settings\Application Data\Microsoft\Credentials
The resolution will remove all cached credentials maintained by IE not just the credentials for the AM website.
