ASP.NET using ADO.NET connection runtime error

[Matt]

I created a simple ASP.NET using ADO.NET application to connect to SQL
Server. However, it produces the following run-time error. I think ASPNET is
the ASP.NET machine account created by VS.NET, and I already added ASPNET in
IIS Manager in directory security tab, and disable the checkbox of anonymous
access. Unfortunately, it still not able to solve the problem. Any good
suggestions?? Thanks!

If you want to use "Integrated Security=SSPI" in the connect string, then
use impersonation.
As you already disabled anonymous, make the following entry in the
"web.config" file, right under the line that says
<system.web> add a line that says
<identity impersonate="true"/>
