We are having trouble access shares from two of our domain contollers using the dns name.  We can access using the fqdn and by IP.  The domain controllers are running DNS and WINS.  When we try to access it just by dns name we get a network path not found error.  You can run a nslookup and the name resolves on those machines.  The domain controllers are server 2008 and server 2008 r2

Any ideas on how to fix this?  Thanks in advance for any help.
