DNS event warnings ID 4521 after SP2 upgrade on MS Servers 2003R2 and SBS2003
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 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.
