The error code 1232 is "ERROR_HOST_UNREACHABLE - The network location cannot be reached." according to MSDN, so it sounds like maybe the IP is wrong, or something else is running as a server on your system and causing a conflict, or network permissions changed or something. Either way we haven't changed the code around this for a long time, and nobody else is reporting problems, so it seems likely the problem is with the network configuration on your machine.
