Domino error updating key ring file

What security setting should I change in Lotus Notes Domino R7?There are two aspects to look at: Agent security settings and Lotus Domino server security settings.

—Mike Lazar, Lotus Notes/Domino Administration Expert Our Lotus Notes 7 and Notes 8 clients are experiencing problems.

We recently added a functionality that lets Notes users select the attachments they want to keep after migrating to Lotus Notes 8.

My Web service is signed with the Lotus Notes ID to run a Web service or agent on the specified Domino server.

In a previous post about troubleshooting a database error, you suggested changing a security setting in Lotus Notes Domino R6.

—Brad Balassaitis, Domino Designer Expert After I synced my Black Berry 7290 mobile device with my Lotus Notes Release 6.5 calendar, I received an Intellisync error, "A Lotus Notes error has occurred.

Please see log for details." When I view the log through the Desktop Manager, it displays the message, "Internal error #4238.The problem is that attachments open on some machines, but not on others.When they don't open, I receive the error message, "Database has not been opened yet." How do I fix this?Generally, Lotus Script code generates this error when it instantiates an invalid database object handle and then tries to work with the object handle.This could be happening if the server and/or file path are incorrect or if the current machine cannot connect to the target server.Translation Canceled." I have absolutely no clue what is causing the Black Berry Intellisync error.
