Event ID 9999 - The DNS Server has encountered numerous run.time events

Hi Experts,

We have the above error on our domain controllers.

Heres the setup:

Domain A - Has two domain Controllers.  
Server 1 - In DNS we have the uk.domain.com forward lookup zone set as a standard primary, with de.domain.com set as a standard secondary.

Domain B - Has two DC's.  
Server 1 - In DNS we have the de.domain.com standard primary forward lookup zone with the uk.domain.com set as a standard secondary
Server 2 - DNS set to have two standard secondary zones, de.domain.com and uk.domain.com

This error shows every couple of hours or so on each server.  Domain B is on a LAN with connection to domain A via a 2MB leased line.

We dont seem to have any problems with comms at all, the only problem is this error showing in the logs.

Initially we had big problems setting the DNS as AD integrated so we went with the file options..

Can anyone provide any idea's??

Many Thanks

as per Microsoft article Q198757

http://support.microsoft.com/default.aspx?scid=kb;en-us;198757

      Event 9999
      Source: DNS
      Description: DNS Server has encountered 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.

CAUSE
The occurrence of these event error messages does not necessarily indicate a problem with the DNS service.

To adjust the level of DNS logging in Event Viewer, use the registry key listed below.

NOTE: In Windows NT 4.0, SP4 or later is required for this key to work.

Registry key:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\DNS\Parameters
Value: EventLogLevel

Type: REG_DWORD

Data values:

0 - Event logging disabled
1 - Only error events
2 - Warning and error events
4 - Information, warning, and error events
For example, if the data value is set to 1, no warning or information events are logged.

-------------------------------------------------------------------------------

I recommend that you check your dns health by using the tools DCDIAG and NETDIAG which come with the windows 2000/2003 support tools pack, which you will find on the OS cd.
