Hi Rob,
Upon the WSAHOST_NOT_FOUND 11001 Host not found (No such host is known. The name is not an official hostname or alias, or it cannot be found in the database(s) being queried. This error may also be returned for protocol and service queries, and means that the specified name could not be found in the relevant database.) error you get, it looks like a connection problem.
I would suggest you to set the hostname of the licensing server instead of using the IP address or finding it automatically. This can be done by using the "Change License Mode" wizard after setting the network license mode in the Configure the Network License window.
I hope that helps.
Best regards,
