More info?)
I'm having the same problem. I have 2 servers running DNS both are win2k
w/sp4, one primary and one secondary. As of 2 days ago they were working
fine. Now if I run DNS on both of them the CPU usage hits 100 percent on both
servers. If I stop the DNS service on either system the CPU usage drops to
about 4% on both servers. I have rebooted both systems with no help. Once
they come up they run fine for 2 or 3 minutes then the CPU hits 100%. There
is nothing in the event logs to indicate any problems. The only events are
informational events not even a warning. I let the systems sit for 2 hours
thinking there may just be some bad replication going on and hoped an event
would be posted but nothing. If I let the systems stay in this state the
servers eventually run out of system resources and become unstable. The
primary DNS server is my DC and the secondary is just a file server. The only
other thing is the secondary server will spikes from 95% to 100%. The primary
stays right a 100%
There is a KB post about this but it is for sp3. I have checked the DNS.exe
version against the version list for the hot fix in the KB and my version is
newer.
