We have two infoblox devices, one a Grid Master 18.104.22.168 and another a member 22.214.171.124.
DNS query is not working when querying from DNS 126.96.36.199 but works if i point to the Grid DNS 188.8.131.52
Everything was working find 12 months since we deployed infoblox not only today the member DNS gave us problem and we had to allow it out to the extern DNS (OpenDNS) manually on the firewall. So it looks like the member is now forwarding DNS request directly to OpenDNS 184.108.40.206 and not passing it through the Grid Master like it usually used to work.
What could be the problem as nothing was changed.
Your help will be highly appreciated.

From reading your post, I believe you confiugred the member to forward recursive queries to the GM and that this stopped working recently. I would take a traffic capture on the member while sending it some queries and also check the syslogs for anything out of place. If you dont find anything useful, you can always create a support ticket with Infoblox.
