I have a .net web app hosting in IIS6 with Windows Authentication and anonymous access disabled. The web app is making connection to a SQL Server that is in the same domain, but on a different machine.

I want to have the IIS Worker process acount I_USR_… to be granted access to the SQL Server.

Will this work ?

(Is there a one to one trust ? Or should I make some extra effort to make the trust work ?)

(edit)
On this page I read:

IUSR_ must be in the domain, and given proper access to the SQL Server; or, you must disable anonymous access on the site / application – which will allow IIS to pass the users’ credentials to SQL Server. Not doing either of these things will result in an error.

    This can work if you provide SQL access to the identity of the application pool.

    There is no way you can pass your users’ credentials to the SQL even with impersonation.
