When our AD server was setup, the DNS name was incorrectly entered as "school.<school-name>.school.nz". It should be in the form of "<school-name>.school.nz". Is it possible to change the DNS name of the forward lookup zones or will this totally screew up our network servers, exchange server and clients?
Our DC and DNS server is running Windows Server 2008. Other servers are a mixture of 2008 and 2003. Our clients are Windows XP.
