I have a msaccess database (.mdb) file. it is located on a network share. The shortcut only points to the mdb, NOT to a workgroup file, yet the users are prompted to login with username and password. This is an old system that was migrated to Access 2013 (most likely not correctly). I need to add users but have no idea what workgroup file this database is pointing to. I looked in the SysWOW64 and System32 folders for System.mdw, but no luck. Any help greatly appreciated.
