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 ?
