Technical details: Could not establish trust relationship with remote server.

Ran into this issue with an old Windows Mobile PDA which couldn't connect to an SSL webservice yesterday.

Unable connect to database. Please contact your system administrator.
Technical details: Could not establish trust relationship with remote server.

The solution might be really dead simple, just check the date and time on the PDA,
if it's too far out of whack it can cause the SSL connection to fail.

You can guess the solution yourself
