RE: Event ID 9999

[Kenny]

Hi,
I have a DNS running on Windows 2000 SP 1 Server and I
alway get this message.

Event ID: 9999 Source: DNS.

DNS Server has encounters numerous run-time events. These
are usually caused by the reception of bad or unexpected
packets, or from problems with or excessive replication
traffic. The data is the number of suppressed events
encountered in the last 15 minute interval.

How do I resolve this?

Thanks in advance.

This depends on the events being logged that are causing this, you will
usually see this logged on DNS servers that have a secondary zone for an AD
primary zone. Everytime a client registers in DNS it advances the serial,
every time the serial advances the secondary does a zone trasfer. If you
have a lot of clients registering in a short time then you will get this
warning on the secondary.
Can you stop the event? Maybe it depends on how your network is set up.
If the warning is cause by continuous zone transfers, you can also ignore it

You will need to find out what event is causing the 9999. In the logs before the 9999 you should see some other DNS errors. These are the ones that need to
be solved to get rid of the 9999. What other errors is DNS reporting? You may also enable DNS logging which reports much more indepth information about
what DNS is going. This can be done by opening DNS manager. Open the properties of the DNS server from the DNS MMC. On the logging tab, enable
every option. This will then create a dns.log file in winnt\system32\dns. Let this run for a day and then analyze the log. Be sure to turn it off though. As this log
can grow quite large on a busy DNS server.

Thank you,
