We have a server using an Access Database as the "back end" for a simple web query form. The clients have no access to the database at all. About once a week, the macros totally get deleted and we have to put them back. We have set the "allowed locations" for macros and allowed macros to run in the Access Database Options. Everything was working fine for over a year and just about a month ago, the macros started getting deleted at least once per week. What could be causing this to happen? They still exist in the system but the front end application stops functioning and we have to re-import them.
