You're probably going to have to trace this starting back at a client 
which is exhibiting the problem. To what nameserver(s) is the client 
pointing? How is that nameserver resolving the name? How is it 
configured (forwarding, authoritative, caching)? If it's forwarding, 
follow the forwarding chain. If it's authoritative, then deconfigure the 
stale zone. If it's caching, then what root servers does it have 
configured?  Follow the delegation chain down from those root servers, etc.
