After installing the latest batch of Windows updates, including an update for ISA 2004, I am unable to open the Companyweb intranet site on the SBS 2003 server with IE 7. It prompts for logon and password but none work, not even Admins credentials. This only happens on the SBS box, all other workstations and servers can bring it up as normal. If I use Firefox, I can logon with Admin credentials. I have tried browsing directly through IIS 6.0, with same result; I get the HTTP Error 401.1 - Unauthorized: Access is denied due to invalid credentials. Internet Information Services (IIS).
Any help will be appreciated.
