I have 2 forward lookup zones in our internal DNS
One is the same name as our website (website.com), It has a CNAME record called 'image' and this points to the root A record of the other forward lookup zone (domain.company.net)
For some reason, over night this record is no-longer resolving.
In fact, if I ping that address, ping can't even find the record.
The only recent change to DNS is that I have added a GlobalNames zone and run the 'dnscmd /config /enableglobalnamessupport 1' command
Does this stop CNAME records pointing to other zones?
I have tried flushing and re-registering DNS and restarted all DNS server services.
Note: All our DNS servers are 2008 R2.
