Your connection string contains the text "integrated security=SSPI", which
indicates that you want to use the Security Support Provider Interface. In
other words, you want to use Windows authentication. This will work fine on
your Windows applications, as long as the user who launched the application
has permissions to the database you are trying to connect to. However, the
account MACHINE\ASPNET (which is the process identity that ASP.NET runs
under by default) does not have the ability to authenticate to another
server (unless you either control the password or else get very lucky),
which is the windows authentication information you are passing. Try
removing this from your connection string if your intention is to use SQL
authentication.
