As you specify "integrated security=sspi" in connection string than I guess you expect impersonating. But for this you should: 1. turn on integrated auth in IIS 2. turn on windows auth in asp.net: 3. turn on imerposation in asp.net:

So, you have been said already it's better to have separated account for SQLSRV connections. Hope this helps.
