This section deals with some of the problems that might arise while trying to configure Bind with Active Directory.
Problem: Some RRset that ought to exist, does not exist.
This message means what it says. The dynamic update request failed because a
prerequisite condition - that some name or group of names (RRset) existed -
did not hold. An NXRRSET error - no such RRset
- was returned to
the client making the request.
Problem: Some RRset that ought not to exist, does exist.
Somebody tried to add a RR(set) using dynamic update which was already present
in the zone. With regards to prerequisite, the condition "rrset does
not exist
" turns out to be false, i.e. the RRset does exist. Since
the condition is false, the prerequisite is not fulfilled.
