Thanks again Barry. Since I'm a tad new at troubleshooting, I'm going
to attempt to provide the data that you require.
Even in the snipet of logs I captured, I can only believe that the "no
such name" was the qdb.domain.com
i'm hoping this is what you were asking for,
Also I could be barking up the wrong tree, but I can't find where that
5 second delay is coming from and the timed dig command with the
+trace at least provides it to me on occasion. I don't see the 5
second with numerous host calls, so again I'm kind of shooting in the
dark (in the dark with data).
