Error using custom app-pool identity for database login

Question

I am new to IIS and MS SQL Server (coming from a Apache MySQL Environment) so hopefully I will include enough details for you guys to help me!

I am converting my web app from using hard coded database credentials (currently SA :/ ) in the Connection String in web.config.

I removed the username and password and put in "Integrated Security=SSPI". The website is configured with a dedicated app pool and that app pool Identity is set to the domain account I want it to use. When I attempt to use the web app I get an error. When I look into the SQL Server logs I see "Login failed for user 'NT AUTHORITY\\ANONYMOUS LOGON'. Reason: Could not find a login matching the name provided.

Any ideas on what I am doing wrong?

Add (or modify) the element below to the system.web section of your web.config.

<identity impersonate="true" />
