With Visual Studio .Net 2003 Final Beta, running under Windows 2000 the
following sample code will take  an error on the following line:

Dim myStream As Stream = myWebClient.OpenRead(uristring)

With an error message of:

"An unhandled exception of type 'System.Net.Sockets.SocketException'
occurred in system.dll

Additional information: An operation on a socket could not be performed
because the system lacked sufficient buffer space or because a queue was
full"

The same code runs without any problem under Visual Studio .NET 2002 on the
same system.

Any ideas on what the problem is?
