Problem DNS ID 4521 Windows Server 2003 R2
Hello everyone long been following events are registered in DNS:
I have 4 DCs Windows 2003 R2 SP2
ID 4521 DNS
ID 9999 DNS
ID 3000 DNS
The most repeated is:
Event ID: 4521
Source: DNS
Type: Warning
Description:
The DNS Server Encountered error 9002 Attempting to load zone.
from Active Directory. The DNS server will Attempt to load this zone again on the next timeout cycle.
This Can Be Caused by high Active Directory load and May be a transient condition.
Do you know how I can fix this?Microsoft Certified IT Professional Server Administrator

HI All,
Thanks for your postings...i tried the above command on my AD+DNS=DC,the warnings are stopped for 1hr..then after it got started again with same 4521 events warning..on my 2 dc which have DNS running...
my server configuration..
Windows 2003 standard sp2..
this alerts are affecting the NAT table of router to fill-in with ips and memory is consuming more on the router...
So i request you all to advice me for the resolution of this error..
