Tried this in as connection string
connectionString="Server=.\SQLEXPRESS;
AttachDbFilename=E:\Database\dnn49.mdf;Database=dnn49;
Trusted_Connection=Yes;"
but i get an error
Unable to open the physical file
“E:\Database\dnn49.mdf”.
Operating system error 5: “5(Access is
denied.)”. Cannot attach the file
‘E:\Database\dnn49.mdf’
as database ‘dnn49’.
What gives?
You must check the SQL Server Service account has modify permissions over the physical file “dnn49.mdf” , and modify permissions also over the folder that contains the file.
