I have an Access 2010 database (Front End) Connected to a SQL Server 2008 R2 Backend. The Database has been in production for over 6 months. All of a sudden yesterday 1 of the tables changed to read-only. To the best of my knowledge no-body did that. I did make some minor changes to a form that is the parent to the form for updating and adding new records to the parent table not the effected table. Changed the label of 1 field and added 2 additional fields to the parent. I can't find any property or setting that's been changed but Even if I don't open the Parent Form and just open the effected table it's still read only. I can't figure out what changed. Any pointer's in the right direction would be greatly appreciated.
