Error Message:

Destination address required.

Explanation:

A required address was omitted from an operation on a socket. In order to connect to or send to a destination address, you need to provide the destination address. This error occurs if the sin_addr is INADDR_ANY (for example, a long zero) in the sockaddr_in structure passed to sendto(). Note: Although connect() and FD_CONNECT also have this error listed, the documentation specifically states that WSAEADDRNOTAVAIL is appropriate if INADDR_ANY is passed as a destination address.

User Action:

Check that you have a name server(s) and/or host table configured. If you are using a name server, use ping to check that the server host(s) are available. Check that the name resolution server application is running by trying to resolve another hostname you know should work. If you are using a host table exclusively, add the destination hostname and address to the table.
