SYMPTOMS
When you use an Internet Services API (ISAPI) filter to implement authentication, you may receive two authentication prompts when you try to access the default document. For example, this behavior may occur when you are using Windows Authentication mode in Microsoft Commerce Server 2002.
CAUSE
The credentials that are supplied in the ISAPI filter when the filter handles the SF_NOTIFY_AUTHENTICATION notification are not used when Microsoft Internet Information Services (IIS) loads the default document. If the default document is not configured for anonymous access, the user is prompted for credentials again.
