besides the fact that when you think "nslookup" is the solution for 
anything you don't know your problem you did not understand my simple 

"dig" or "nslookup" or whatever is just a client talking to a dns server 
on port 53 - that's it - it won't debug your server and if it would be 
able to do so your server would leak informations classified as security 
hole which needs to be closed
