Cause
This error indicates an SSL handshake failure between the Windows 2003 server and the Authentication Manager server when trying to initiate the session from within the SDK sample.
The SSL handshake is failing because Windows 2003 does not support any of the ciphers used by the Authentication Manager server on port 7002.
Resolution
This can be resolved by applying
Microsoft Windows Server kb 948963 / Hotfix 192447 (Cipher Suite upgrade) bad link which enables the
TLS_RSA_WITH_AES_128_CBC_SHA and
TLS_RSA_WITH_AES_256_CBC_SHA ciphers which are used by the Authentication Manager server on port 7002.
