I am getting the below error from VS on an 32-bit XP Professional server even though I set Tools->Options->Database Tools->Data Connections to “SIDEKICK”, which is the name of my computer. In other words SIDEKICK should default to the full SQLSERVER.
In other words, I want VS to use SQLSERVER instead of SQLSERVER EXPRESS. And I can clearly see my database both from VS in the Server Explorer and also in SSMS 2008. Furthermore, I can view the tables of this database in Server Explorer from VS. I do not get any build errors. And it looks like all of the naming is consistent in my web.config file.
I am developing my website according to a Microsoft tutorial, so I should not be getting an error. Yet I get the following exception when I run this code below:
CreateAccounts.aspx.cs file
protected void CreateAccountButton_Click(object sender, EventArgs e)
{
MembershipCreateStatus createStatus;
//This line below is where the exception occurs
MembershipUser newUser = Membership.CreateUser(Username.Text, Password.Text, Email.Text, passwordQuestion, SecurityAnswer.Text, true, out createStatus);
And here is what the exception looks like:

And I turned off the Firewalls also, so I know this is not the cause.
What protocols do you have enabled in “SQL Server network configuration” inside “SQL Server Configuration Manager”?
