SYMPTOMS
Consider the following scenario:
- A Microsoft Windows Server 2003-based primary Domain Name System (DNS) server hosts several primary zones.
- A Windows Server 2003-based secondary DNS server hosts the corresponding secondary zones.
- The secondary DNS server sends out DNS start of authority (SOA) query records to the primary DNS server when the DNS service restarts on the secondary DNS server. All DNS SOA query records use the same 0x6000 DNS ID.
- An application firewall that examines the ID field in the DNS packet header is located on the network between the primary DNS server and the secondary DNS server.
In this scenario, the firewall may block zone transfers from the primary DNS server to the secondary DNS server.
Note This does not affect manual zone transfers.
