One of my schools has just been upgraded tom Access 2003 to Access 2010. Their database is on a shared network drive accessed by about 10 simultaneous users. This all worked fine until the upgrade and they have told me they saw a message about security and clicked Yes helpful support information but that's all I have. Now what happens is the first user accessing the database can open by double clicking the database icon but all others after the ldb file is created have to run Ms Access and then select File > Open.
They are also getting multiple backups being created automatically.
Any help appreciated.
