Access Changes OS Security

[AlanDI1]

I have an Access database with an Autoexec macro that runs code that reads Outlook/Exchange information and populates a table. It runs nightly and the table is read by ASP code for display on an intrannet site.

All works fine. When Access runs nightly (or you run the database by double clicking it) it changes the OS level security (as shown in (right click file name) properties/security).

I want Everyone in that list so the ASP code will run. Why does Access remove Everyone from the list and how do I stop it?

Thanks
