SYMPTOMS
Incremental zone transfers that are requested by Windows 2000-based secondary servers from a Bind primary may not succeed. When this occurs, event ID 6524 is recorded in the DNS event log.

Sample DNS event ID 6524 record:

Event Type: Error

Event Source: DNS

Event Category: None

Event ID: 6524

Date: 4/18/2000

Time: 10:55:48 AM

User: N/A

Computer: MYCOMPUTER

Description: Invalid response from master DNS server at 192.168.0.10 during attempted zone transfer of zone test.microsoft.com. Check The DNS server at 192.168.0.10 and insure that it is authoritative for this zone. This can be done by viewing or updating the list of authoritative servers for the zone. When using the DNS console, select zone test.microsoft.com Properties at server 192.168.0.10 and click the Name Servers tab. If needed, you can add or update this server in the list there. As an alternative solution, you could also modify settings in the Zone Transfer tab to allow transfer of the zone to this and other DNS servers.



CAUSE
The Bind server is not sending back a response of type &quot;Incremental zone transfer.&quot; This causes the transfer not to succeed because the response type must match the query for zone transfers.



MORE INFORMATION
For additional information about the response format for incremental zone transfers, see RFC 1995.
