I am running one SBS2003 server and one Windows 2003 R2 Server.  I upgraded both to SP2 last night, after the upgrade the DNS event logs on both servers are generating warnings every 3 minutes as follows:

The description for Event ID ( 4521 ) in Source ( DNS ) cannot be found. The local computer may not have the necessary registry information or message DLL files to display messages from a remote computer. You may be able to use the /AUXSOURCE= flag to retrieve this description; see Help and Support for details. The following information is part of the event: 9002, ..

The active directory and file replication logs are fine.  I can't find any information on this warning.  Please help me find out what it is and how to correct the problem.

post your ipconfig /all result, please. If the configurations are good, then check with MS if they have any updates/fixes. I've seen a few more same issue after sp2 upgrade.

what do you mean by "normal"? is it using the 127.0.0.1 as DNS server? Is it using an external DNS server? etc.

better yet, post a netdiag /v result

I had a similar problem.

I was getting this in my event log every three minutes.

EventID 4521, error 9002. 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.

The "." zone is the DNS Cache. It needs to be changed from AD-integrated to a file zone.  It seems SP2 screws this up, big suprise!!!

Here is how I fixed it.

On the properties for your DNS Server Change the "Load zone data on startup" from AD +
registry to just registry. Then stop and restart the DNS service and that should take care of it.

I searched for hours for this fix and it worked instantly for me.

Now DNSCMD /ZoneInfo shows that the cache is no longer AD-integrated but file based which immediately stops the problem.

-Thanks to a guy named Ron for pointing me in the right direction.
I hope this saves some people some time!!!

For those looking for the "Load zone data on startup" it's an option in the "Advanced" tab.
