Our .NET 2.0 app relies upon the ability to download xml webpages from URLs.  At startup, we have about 6 boxes in the wild (out of thousands) that are seeing the following inner exception when they try to download an xml page.  System.Net.WebException: The underlying connection was closed: An unexpected error occurred on a receive. (Inner: ) System.IO.IOException: Unable to read data from the transport connection: An existing connection was forcibly closed by the remote host. They can get to the URL in their browser just fine, so we know our server is working.  Furthermore, the embedded WebBrowser control in our app can pull up webpages just fine, so I don't think their firewall is blocking our app.  I'm hoping it's just some diagnosible configuration issue.  Here is the snippet of code that does the downloading: WebRequest request = WebRequest.Create(fileToDownload.SourceUri);request.CachePolicy = new RequestCachePolicy(RequestCacheLevel.NoCacheNoStore);request.Timeout = (int)DefaultTimeout.TotalMilliseconds;request.Method = "HEAD";WebResponse response = request.GetResponse(); Nothing revolutionary there. (I've also tried it without the HEAD request, without keepalive, and using HTTP 1.0).  And here is the exception: System.Net.WebException: The underlying connection was closed: An unexpected error occurred on a receive.

I'm using Visual Studio 2008, and my database is SQL Server 2000. I want to add a connection to the Server Explorer in VS. The Data source is Microsoft SQL Server (SqlClient). After entering in all my information and I click Test Connection, it is successful. But when I click OK, I get the error: Unable to add data connection. ExecuteScalar requires an open and available connection. The connection's current state is closed.What's going on here?
