I am developing a simple Asp.Net website and am having trouble with my SQL Server connection/configuration. My web page has a GridView that should display my table info. When the page comes up I get:

Cannot open database "Test" requested by the login. The login failed.
(depending on the other changes I've made I get one of the following:)
Login failed for user 'NT AUTHORITY\IUSR'
Login failed for user 'NT AUTHORITY\NETWORK SERVICE'
Login failed for user ''

My particulars are: Asp.Net 3.5, C# 2008, SQL Server 2008 Express, IIS 7.

My SQL Server Properties are:
Authentication Method = Windows Authentication,
I've tried both Server Authentication methods: Windows Authentication mode and SQL Server and Windows Authentication mode

I can create the SQl Data Source fine, it points to my web.config file as:
<connectionStrings>
<add name="TestConnectionString" connectionString="Data Source=BUSHKILL-PC\SQLEXPRESS;Initial Catalog=Test;Integrated Security=True" providerName="System.Data.SqlClient" />
</connectionStrings>

I've tried adding this with no luck:
<system.web>
<identity impersonate="true" />
</system.web>

I've also tried changing to "Integrated Security=False" with no luck.

I've looked at many forums and tried many different things with no luck, I'm guessing that it's a certain combination that I just haven't hit on correctly, can anyone help please?

Thanks, Joe.
