Since both my machine and the Elog server PC are inside my company's "security zone", I am not running a firewall on my machine.

For what it's worth:  in trying to research the "No error" message, I did come across this information on MS's website; that is, their statement is:

The gethostbyname function retrieves host information corresponding to a host name from a host database.

Note  The gethostbyname function has been deprecated by the introduction of the getaddrinfo function. Developers creating Windows Sockets 2 applications are urged to use the getaddrinfo function instead of gethostbyname.
