When I try to access my SQLExpress database using a .NET web page I get the following error:
Cannot open database <dbname> requested by the login. The login failed.
Login failed for user 'IIS APPPOOL\.NET v4.5'
This started happening after I updated the database. Before the update everything connected without issue.
.NET v4.5 has cull control of the folder containing the database, the mdf file, and the log file.
Any suggestions what I have wrong?
