Event IDs 4521 & 9999 repeatedly in event log

I have a W2K3 domain with 2 DCs running Server 2003 in native
mode(workstations are all XP). When I check the event log I get these two
events repeated every hour. Any advice greatfully accepted.

Source DNS Event ID: 4521
The description for Event ID ( 4521 ) in Source ( DNS ) cannot be found. The
local computer may not have the necessary registry information or message DLL
files to display messages from a remote computer. You may be able to use the
/AUXSOURCE= flag to retrieve this description; see Help and Support for
details. The following information is part of the event: 9002, .


immediately followed by:-

Source: DNS Event ID: 9999
The DNS server has encountered numerous run-time events. To determine the
initial cause of these run-time events, examine the DNS server event log
entries that preceded these run-time events. The data is the number of events
that have been suppressed in the last 60 minute interval.

Further to my first post, both servers have DNS installed and running and
both of them are showing these warnings/errors in the event log.

I googled around on this one and someone suggested creating a primary zone
called "." and making it registry only then switching it to AD. I tried that
but get a pop up message saying there has been a 'Server Error' when I change
to zone to being AD based but no entries in the event log.

I am considering switching both servers to Registry and saving the zone
files in \system32\dns and then uninstalling DNS from both servers,
reinstalling and starting again. I can't see what has caused this problem as
it was fine when these two servers were set up new in March this year.
