Summary

This article (KB953317) provides a fix for an issue in which there are no records in a secondary DNS zone and DNS Error 6527 is logged on a Windows Server 2008 server. For detailed information about this missing records issue, see the “Symptoms,” “Cause,” and “Resolution” sections of this article. To download the fix for this issue, click the View and request hotfix downloads link that is located on the upper-left of the screen.

Symptoms

Consider the following scenario:

  • You create a primary DNS zone on your Domain Name System (DNS) server.

  • You enable Zone Transfer on the DNS zone, and you allow Zone Transfer for all the servers.

  • You enable Dynamic Update on the DNS zone.

  • A very large number of changes occur on the primary DNS zone.

In this scenario, all records are missing from the secondary DNS zone except the start of authority (SOA) records.Additionally, the following error message is logged on the Windows Server 2008 server:Event Type: Error Event Source: DNS Event Category: None Event ID: 6527 Description: Zone msprod.msp expired before it could obtain a successful zone transfer or update from a master server acting as its source for the zone. The zone has been shut down. For more information, see Help and Support Center at http://go.microsoft.com/fwlink/events.asp.

Cause

This issue occurs because the primary zone file cannot transfer to the Windows Server 2008-based secondary DNS server when the primary DNS server has a very large number of changes. During the DNS Zone Transfer, the secondary DNS server requests an incremental zone transfer (IXFR) of the zone. When a very large number of changes occur on the primary DNS server, the primary DNS server cannot service an IXFR query. Instead, the primary DNS server responds to the IXFR query with a full zone transfer (AXFR) response. The secondary DNS server ends the transfer because it expects an IXFR request and not an AXFR request. Because the secondary DNS server is never able to complete a zone transfer, all records in the zone on the secondary server eventually expire. Therefore, there are no records in the secondary DNS zone.
