An RRset is a resource record such as A, PTR, CNAME, MX, etc. The
client is trying to add an A record called protect1.domain.com. with an
IP address of 24.5.78.100. This looks like a name server issue, so
you'll need to turn on debugging for dynamic updates on the dns server
and see what named is complaining about. The BIND Administrator
Reference Manual is online at http://www.isc.org.au/sw/bind (scroll
down to the documentation section towards the bottom of the page).
