 But... What does dnscache log on to? ;-)  
It would be nice to know what is going on in non-forwarding mode.

I will check with campus IT on the DNS root server blocking issue...

BTW, both modes work through my ISP.
Thanks agin.
Rick.

this is possibly a shot in the dark...

AFAIK dnscache in _not_ forwarding mode uses the root servers to find 
suitable name servers. This may be blocked on your campus, so forwarding to 
the campus DNS server will solve this problem.

I guess its meaning is _dnscache_log_on_

client-server server-server is on zone transfers.

Bind is a completely different animal, rather complex and without knowledge 
_what_exactly it is you want to do I would frown on this. I guess you would 
find ample help at the IT staff on your campus to set up Bind.

Then, why set the Bind box _outside_ your LEAFed perimeter? DMZ might be a 
good idea.
