Diagnosis help

[Jon Booth]

My zone lucidlogic.com is having a problem with one of the hostnames.

europa.lucidlogic.com is resolving here but ganymede.lucidlogic.com is
not.

Can anyone see why?

How do I know which nameserver (primary or secondary) nslookup is getting
its info from?

Thanks for any help
Jon
