Multihomed DNS Server May Fail Recursive Queries

• Microsoft Windows NT Server version 4.0

SYMPTOMS

You may not be able to reliably resolve recursive queries from your Windows NT Server Domain Name Service (DNS) server when all of the following conditions is true:

• Your DNS Server is multihomed, having multiple IP interfaces.



• DNS is not bound to all of the adapters in the computer.



• The adapters in the DNS server are connected to disjoint network segments.

CAUSE

The DNS server cannot consistently choose which network adapter to send and receive queries on under this configuration. DNS may either try to send on an adapter that does not have DNS bound to it or try to send packets on an adapter not reachable by the querying DNS client hosts.

RESOLUTION

Verify that DNS is bound to all adapters in your multihomed computer.
