I have multiple users reading from the SQL database which I manage access by SQL permissions. SQL database storage makes this a killer app. From time to time I am required to restore the mRemoteNG database to be able to use the tool. I can see the data in the database directly but the application can't read it. I restore the contents of the database to get the data in usable form. All users that use this application have readdata access only so it shouldn't be caused by a rogue update to the data.
