SYMPTOMS
When Microsoft Windows Server 2003 Domain Name System (DNS) requests an incremental zone transfer from a Berkeley Internet Name Domain (BIND) server, the following events are logged in the system event log: Event 5501

Source: DNS

Type: Warning

Description: DNS Server encountered bad packet from. Packet processing leads beyond packet length.

Event 6524

Source: DNS

Type: Error

Description: Invalid response from master DNS server at  during attempted zone transfer of zone. Check  and ensure 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  Properties at server   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, where  is the name of your DNS server,   is the IP address of your master DNS server, and   is the name of your DNS zone.

However, a full zone transfer is completed correctly when you click Transfer from Master in the DNS console.



CAUSE
This problem occurs because the BIND server sends a full zone transfer instead of an incremental transfer. A full zone transfer contains a start of authority (SOA) record at the start of the transfer, followed by the records, and then the second SOA record at the end of the transfer.

After DNS receives the second SOA record, DNS automatically switches to a full zone transfer. However, DNS then detects the first zone record as the SOA record. Because of this, DNS incorrectly detects a bad packet and reports the bad packet error as event ID 5501 and event ID 6524. DNS then ends the zone transfer.
