DNS Issues on SBS 2003 R2

Tech-Archive recommends: Speed Up your PC by fixing your registry



Hello everyone! I am having some wierd issues with a SBS Server. The
DNS Server is crashing periodically. I get a few errors and then it
crashes.

This is the start of the last crash. I will list the errors on the
server at about the same time:

Event Type: Warning
Event Source: DNS
Event Category: None
Event ID: 3000
Date: 4/25/2007
Time: 5:51:17 AM
User: N/A
Computer: SWYATT001
Description:
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 precede this event. To prevent the DNS server
from filling the event log too quickly, subsequent events with Event
IDs higher than 3000 will be suppressed until events are no longer
being generated at a high rate.

This keeps going in like a cycle on and on and on!

The Errors don't really tell me much. A reboot always fixes the issue
but this happens almost weekly. Never the same time but it is rather
consistant.

Any help would be apperciated.
