Answer 1

Giving the sql service account 'NT SERVICE\MSSQLSERVER' "Full Control" of the database files

If you have access to the server files/folders you can try this solution that worked for me:

SQL Server 2012 on Windows Server 2008 R2

1. Right click the database (mdf/ldf) file or folder and select "Properties".
2. Select "Security" tab and click the "Edit" button.
3. Click the "Add" button.
4. Enter the object name to select as 'NT SERVICE\MSSQLSERVER' and click "Check Names" button.
5. Select the MSSQLSERVER (RDN) and click the "OK" button twice.
6. Give this service account "Full control" to the file or folder.
7. Back in SSMS, right click the database and select "Properties".
8. Under "Options", scroll down to the "State" section and change "Database Read-Only" from "True" to "False".
