Sounds like you're right on with that thought.  Seems to me that when
the first DNS fails it would go to the tertiery DNS and would work
fine.  And from reading what you put about the log files not having a
lame server... that would just make sense seeing as the DNS didn't exist
to tell your PC where it was!  hehe.  Good luck, I'm sure things will
work out well for you. =20
