In fact you don't resolv at all. Can you provide:
dig einsccmdp-01.tio.nl +trace +cd
dig @172.16.208.10 einsccmdp-01.tio.nl
(this one to eliminate 172.16.208.10 beeing broken)
I don't understand why you define staf.tio.nl and student.tio.nl as
tio.nl is already on the same forwarders. I don't know if it's valid but
it seems useless. And your logs suggest a problem between staf.tio.nl and
tio.nl. Could you comment staf.tio.nl and student.tio.nl, restart bind
(or reload + flush) and try again above dig ?
