I have some access applications that connect to a SQL Server database. The applications were written for Access 2003 and now are running on 2010. We are now getting this message:

It say “Missing Security Profile” No Security Profile has been set up. If I click OK then the application runs fine.
This sounds like it may be to do with user level security having been set up at some stage. You might also check that
...\AppData\Roaming\Microsoft\Accesscontains a filesystem.mdw(Vista/Windows 7). This is the default security file and is referenced in the connect string in Access 2010.
