Problem: Internet Explorer 8 won’t remember the user’s password information for a website
User starts IE8, types in “salesforce” in the address bar, which automatically brings him to to Salesforce.com. He clicks on the Login link, enters his Username and Password, checks off the box that says “Remember User Name”, and goes about his work. Afterwards, he closes out IE8 and then reopens it later on. He proceeds to Salesforce.com again, but it takes him to the login page and prompts for the password (User Name field is already populated). It should remember his password and log him in automatically.
What did work was deleting all the salesforce.com bookmarks from the user’s Favorites!
