DNS Querry

Simple query and recursive query both fail consistently. Periodically some domains won't resolve without www and sometimes they will only resolve without www.  Where do I start?  Last servers were windows 2000 systems and I never had any problems.  I scrapped it and built a new 2012 server and am having these problems.  I use my new server for primary DNS and Gandi for secondary.  What info do I need to post?  Here is an ipconfig to start with.
