DNS Server Warning Events 9999 and 4521

Hi all ,

My DNS events log is full of the following warning events 9999 and 4521 which are :

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.

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, ..  

Why these warnings happening too much this way?? and how can I get rid of them ???

1 Solution
The first event is information that login to the event log was stopped.
The second event can be solved with the following command.
dnscmd /config /bootmethod

Good luck,
This can sometimes occur after SP2 is installed. As wwwally states running
dnscmd /config /bootmethod
from the command line normally fixes the problem

This command worked like a champ. I have to say though the reason for my error 4521 showing up was that I was remotely managing the server and accidentally opened two TS sessions to the box and created the new zone. Upon checking the event logs I noticed the error. After looking at everything I went to look at the time and noticed the two connection tabs. Once I properly logged off of one of the sessions, I was able to successfully execute the command and load the new zone.
