    I have 2 websites that I am running in localhost. 1 is the main web app and the 2nd is the telerik reporting application.
    My connection string looks like this:
    Data Source=.\SQLExpress;AttachDbFilename=C:\ODI\ODI_AGBSafety.mdf;Trusted_Connection=Yes;

    I keep getting the following error and don't know what to do

    "CREATE DATABASE permission denied in database 'master' An attempt to attach an auto-named database for the C:\ODI\Example.mdf failed. A database with the same name exists, or specified file cannot be opened, or it is located on UNC share. 

    Any help would be greatly appreciated.

    Hello Chad,

    Please verify the connection strings is correct - Attach a database file on connect to a local SQL Server Express instance. Then check if the path to the database is the correct one on the server, where the application is deployed. Finally grant access to the running process to access the database, which can be done trough the used application pool.

    Let us know if you need any further help.
