how to check if a slave zone is expired

[hugo hugoo]

Marc,
 
This example was maybe not the best one.
My questions remains as other zones are well unavailable on all name servers.
 
Regards,
 
Hugo,

Hugo,
 
This must be a configuration error on “ns2.skynet.be.”
The other 3 authoritative name servers answer fine, for omega-pharma.be;
ns2.skynet.be. returns the list of root name servers, meaning it isn’t configured to be slave for that domain.
 
Contact Skynet/Belgacom helpdesk to get this corrected.

Kind regards,

Dear all,
 
Is there a way to check that a slave zone is expired?
I use dig in the following way to see that the zone is not responding on my server...but is this due to the fact that the zone is expired or another problem?
 
dnszone002:/etc/bind/zones/slave# dig @localhost omega-pharma.be soa
 
; <<>> DiG 9.3.4 <<>> @localhost omega-pharma.be soa
; (1 server found)

.                       518400  IN      NS      M.ROOT-SERVERS.NET.

 
- How can I see that it is because the zone is expired? 
 
- Is there a way to visualise all the zones that are expired (to make a cleanup of the configuration)
 
 
Thanks for your feedback,
 
Hugo,
