Quest: Error connecting to MSDE hosted DB...

[lewi]

I am trying to connect to MSDE hosted DB on the same computer as my ASP.NET
app. The DB was created using VS.NET Server Explorer window and here is my
aspx.cs code in the Page_Load() for the main page...

Note: using "using System.Data.SqlClient;"

try
{
SqlConnection dataConnection = new SqlConnection();
dataConnection.ConnectionString = "Integrated Security=true;Initial
Catalog=mydb;
Data
Source=MYSYS\\VSDOTNET;";
dataConnection.Open();
...
dataConnection.Close();
}
catch(Exception SQLException)
{
Console.WriteLine("An Database error occurred - " + SQLException.Message
+ "...");
}

Now when I call(a breakpoint set in the catch block) SqlConnection::Open() I
get - SQLException.Message == "Login failed for user 'MYSYS\ASPNET'" in the
varibles window...

Now I have tried adding ASPNET and SQLDebuggers account to the site
folder(site is outside of wwwroot) and to the IIS operator acoount tab of
the site properties box and there is no change...

What am I doing wrong here and why is it thinking I am user MYSYS\ASPNET...

Any help...
