What could be possible cause for this error "Could not establish trust relationship for the SSL/TLS secure channel with authority 'sharepoint04'. Details: The underlying connection was closed: Could not establish trust relationship for the SSL/TLS secure channel.". I could see one resolution at this link http://support.sas.com/kb/45/853.html but im using iis 7.5 so this does not apply to me. Also is it possible that similar error will come if i try to use sas web parts 1.1 with sharepoint 2010? Will this resolve if i use 4.3 or higher version? please help
