I am developing ASP.NET 2.0 application using SQL Express 2005. I have attached my database with the application.
The Connection string:
<add name="WCMIRConnectionString" providerName="System.Data.SqlClient"
connectionString="Data Source=.\SQLEXPRESS;AttachDbFilename="\App_Data\WCMIR.mdf";Integrated Security=True;Trusted_Connection=no;User Instance=True" />
When trying to connect the following error appears :
Cannot open database "dp-name" requested by the login. The login failed. Login failed for user 'Machine\useID'.
How can this error be resolved?
