Consider the following scenario:
System.Net.Sockets.SocketException: A socket operation was attempted to an unreachable host
When you use IPv6 addresses on a computer that is running Windows XP or Windows Server 2003, the Microsoft .NET Framework removes the zone ID from the Uniform Resource Identifier (URI) before the remoting application connects to the server.
When you use IPv6 addresses on a computer that is running Windows Vista, the .NET Framework remoting application uses the local sub-net if the zone ID is not specified. Therefore, this problem does not occur on Windows Vista.
