After following KB9691 on how to configure Windows Authentication for Strategy Office 9.2.1 when Strategy Web Services 9.2.1 is hosted on a Windows IIS server, users are still unable to login. When users attempt to retrieve the list of projects for the project source configured to use Windows Authentication, users are prompted with one or both of these error messages:

0x800411c7: (Cannot login by using the NT User account. Please ask your administrator to link this NT User account to a Strategy Intelligence Server User or set the Web server properly).

Unhandled exception has occurred in a component in your application. If you click Continue, the application will ignore this error and attempt to continue. InvalidArgument=Value of '0' is not valid for 'index'. Parameter name: index.
