256986 Description of the Microsoft Windows Registry
SYMPTOMS
A service that is running in the Microsoft Windows operating system context cannot make a Secure Sockets Layer (SSL) connection by using Microsoft Secure Channel (SChannel) authentication with a default client certificate. For example, this scenario may occur when you are configuring a Microsoft Exchange Server Simple Mail Transfer Protocol (SMTP) connector to use the Transport Layer Security (TLS) protocol.
CAUSE
This problem occurs because SChannel looks for the default client certificate in the following registry subkey:
HKEY_USERS\.Default\Software\Microsoft\SystemCertificates
However, the default client certificate is stored in the following registry subkey:
HKEY_LOCAL_MACHINE\Software\Microsoft\SystemCertificates
