Our Netware 6.0 DNS serves our AD domain. I am adding a new DC and need to
create the SRV records in DNS.

Is there a way I can merge the required underscore records (_msdcs etc) from
netlogon.dns into Novell DNS or do I need to export the existing primary
zone, edit it to include the new server details, delete the existing primary
zone, re-import? If I need to delete the existing zone are there any
gotchas? Can I do this on a live system with no worries? I know I would need
to increase the serial number in the BIND file and re-load named.nlm.
Would it be safer to enter the information by hand via the DNS GUI?
