    ... and netbackup with unresponsive dns is a bad place to go...it grinds to a halt with many functions.

    Might help if you can clarify how your dns is set up and why it "only connect half the time". Sounds unusual!

    In my experience, I root out round-robin DNS entries - I've always had a bad time with them.  It's one of the classic initial steps of debugging client -> media server connectivity is to check whether round robin DNS exists and if found get it removed.

    Don't use any DNS that answers only half the time (normal or round robin).

    Netbackup rely heavily on DNS. its my assumption the built-in DNS cache is not supposed to recover from missing DNS respond but to lower the amount of DNS request sent. After all you never know if the "missing" DNS reply is for something new or something known - so to say. 

    Bottom line - you need perfect working DNS servers when using Netbackup.
