Connection Error

Error Message:

A connection was successfully established with the server, but then an error occurred during the login process. (provider: TCP Provider, error: 0 - An existing connection was forcibly closed by the remote host.)

The error occurs in Visual Studio 2005 v 8.0.50725.42. I have my string in my web.config file. In Visual Studio it doesn't work. When you upload the page it connects and shows the data. Now, I have been several places and been asked, "So what's the issue?" The problem is that I want Visual Studio 2005 to connect so that I can use it to create Gridviews, use the Server Explorer and so on.

Is there an upgrade to VS2005? Is this a known bug? Is there a work-around - a configuration that needs to be setup in the web.config file? I've only just begun my .NET 2.0 experience so type slow and use small words...

Thanks!
