The system function gethostbyname() failed to find the client's host name.
Group of backups failing. All point at the same cluster. Policies use virtual names. NSLookup to virtual names fail but the FQDN succeed. Pings to both from Master work. NSLookup and ping from client work as well. Can connect to all clients in Host Properties. Verfied that correct entries are in the hosts files. Status is 48. Followed the recommendations in the troubleshooter in Activity Monitor and it didn't make a difference.
