I recently moved an order processing database from one server to another. This database is the source for linked tables in other databases. Everything works for several hours, but eventually this error occurs when accessing data on the linked tables:
3356 Autoload You attempted to open a database that is already opened exclusively by user Admin on machine FS04. Try again when the database is available.
I have relinked all tables and refreshed all links. This was never an issue on the old server, and no database security changes were made.
