I tried once again to set up a DataSet in Visual C# to the SQL Server 2005 Express Beta 2 I have installed on my own PC. I don't even get to 1st base.

Here's the error I receive every time. I've already uninstalled it once and re-installed it.

A connection was successfully established with the server, but then an error occurred during the login process. (provider: Shared Memory Provider, error 2 - Connection was terminated.)

Any ideas how I can establish a connection to SQL Server 2005 Express using Visual C#?
