I gave a user a new computer. He had XP before and now has Windows 7. We have a web interface developed in classic ASP. He can access that fine. But one of the links on that interface points to an excel file stored on the server (the same server hosting the interface app). When he clicks on that he is prompted for a password (which should not happen). If you cancel out of the loginit will open the excel file anyway. If you enter the correct password it will not accept it. The login prompt is showing the correct domain. But entering the correct user name and password will not work – it will prompt again and again unitl the user is logged out for the failures. Note that the excel document is on the same server hosting the web app that links to it and the user can access the web app with pass-through authentication. He is only having this problem when he tries to open the excel file. The excel file is in an older version than what he has installed, but he has the compatibility pack installed.
He has integrated windows authentication turned on in IE. He is NOT prompted for a password for any other activity on our site. He has the same file level permissions he had before and the same as everyone else and they are perfectly fine.
Does anyone have any suggestions?
