Your host is not having authority for its zone delegated to itself.

priority1res.com	nameserver = FRED.CAMCO-MFG.COM
priority1res.com	nameserver = BARNY.CAMCO-MFG.COM
FRED.CAMCO-MFG.COM	internet address = 216.240.45.189
BARNY.CAMCO-MFG.COM	internet address = 216.240.45.190

You can make whatever changes you want on your system, and nobody but
you will ever see them unless Fred and "barny" also display them.
