We strongly recommend that all users upgrade to Microsoft Internet Information Services (IIS) version 6.0 running on Microsoft Windows Server 2003. IIS 6.0 significantly increases Web infrastructure security. For more information about IIS security-related topics, visit the following Microsoft Web site:

SYMPTOMS
The Certificate Mapping feature does not work when Internet Information Server (IIS) version 4.0 is installed on a server with the system locale set to French. If you set up some mapping definitions, the settings remain valid until you restart IIS. However, after you restart the IIS Admin service, the mapping list is empty and all of your settings are lost.



CAUSE
This problem can occur because on startup, IIS checked the session key in an incorrect way that only appears as an error when using the default system locale is set to French.
